Personally I don't like to lift wheels off the ground with the jacks and I would never lift the drives off the ground. If it's so unlevel that the wheels would be off the ground, I'll run up on some boards first to get close, then finish leveling with the jacks. Fronts are ok. You won’t damage anything. As stated above, never the rears (drive wheels) because the parking brakes are on the rears. If you’re not comfortable with the fronts being off the ground, you can build some small ramps or wood blocks you can drive the front wheels onto. If you search for ramps on this forum you’ll find lots of examples. When an air bag RV is lifted, ONLY the axle weight is left on the ground. no matter the lift height. This is unlike a leaf or coil spring vehicle. The tires provide limited stopping. If the leveler pads are on softer ground, they will put much restriction to the RV moving sideways as the pads will be in a hole. The suspension system has no problem handing from the shocks / limit straps. It endures FAR greater stress while you are driving down the road soaking up the bumps and road heaves. All that being said, try to NOT lift the RV any further up than is required. Things inevitably break. Hydraulic lines, solenoids, seals etc. You don't want a single leg to drop on it's own which the torques the chassis. An RV up in the air is invitation to crawl underneath or store stuff under. Not good when something breaks. So, pick a more level spot or use blocks to get the rig as level as you can before lifting. Don't park on a hill and lift so that there is no chance of slipping sideways (tire and / or leveling pad friction). Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times... I don't like to lift either off the ground ever. I only use the jacks enough to level the final little bit and to not have the coach shake while moving around in it. The thread Sonic posted is great! I use 2x10s like suggested in the posted link, but took it slightly further. I didn't cut an angle, don't really need it and in the past I found that it sometimes gives them the ability to slip while driving onto them. I would post pictures but it is in the shop for engine repair and the boards are in unit. Basically I took 2x10s and cut 2 boards the longest that would fit in the bay I was storing them in (about 36 inches long). I then cut 3 more boards about 8 inches shorter (for a total of 4 boards high), so lenghts of, 12, 20, 28, 36 long. I have 2 sets in case there is a need for the rear duals to go on boards. To keep the boards from sliding when driving onto them, I bought 3 different size carriage bolts that would go through 2, 3, or 4 boards but not all the way through, just long enough to keep them stable as you drive. I then took a spade bit that was 1/8 inch larger than the bolts and drilled through all 4 boards to accommodate the bolts, i did this in the rear where they would line up even and no worry about puncturing tires if they popped up slightly. I then took a spade bit slightly larger than the bolt head, and drilled on top of the holes the thickness of the bolt head. This way they sit down flush with the boards. It works very well! For the jack pads, I couldn't use anything very thick, as if I am on level ground and I dump the air, I only have about 4 inches between the jack pad and ground. I took 2x4s, and cut them the length of 3 2x4s put next to each other. I cut 6 in total. I then laid them crossways (think the first 2 layers of Jenga) and nailed them together from both sides. These work great for leveling! When i get it back from the shop next week I will try to remember to post some pictures. Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times...

Loopwheel
'I first made myself a mountain bike wheel, and it was incredibly noisy and wouldn't steer - but it worked.
The story of loopwheels is one of determination, and a streak of madness. They were invented and developed by Sam Pearce, in his home in Nottinghamshire, England. By training and profession, Sam is a mechanical engineer and industrial designer. By nature, he is some one who loves making things: designing, building, doing. He loves simplicity, and products that work well. Sam is practical and hands-on. He is stubborn and doesn’t give up easily. All useful traits when you find you’ve set out on a journey to reinvent the wheel . . .
In today’s full-suspension mountain bikes, the front and rear shocks do excellent jobs lessening those impact forces. And that helps keep riders logging miles and turning switchbacks.

Speaking with Gemma and Sam, the brains behind Loopwheels it is clear that you are speaking to a pair of very passionate people.
Loopwheels are designed with suspension within the wheel itself: in place of rigid spokes, they have three loop-shaped springs.

In the 20 minutes I was riding them, I had a blast. It really was as simple as that, they where a real hoot to ride.
In a Globe story this February, reporter Eric Moskowitz noted that Boston fills approximately 19,000 potholes in an average winter, and that the city has gone as far as developing a new app, called Street Bump, that attempts to give drivers the ability to instantly notify City Hall when a new crater appears. And that's just the city of Boston. Do the math and consider how many gaping holes have appeared in the New England region after last winter's prodigious snowfall.
Just purchased a 2nd Traxion for my wife; after she borrowed mine she had to have one. This one arrived in perfect condition via UPS. Had to fine tune the brakes and shifters but that is easy. The people here having pedal/crank problems are causing the problem themselves by installing them dry and severly over tightening them. Put a little grease on the threads and take them down to just beyond finger tight. They are threaded opposite of the crank rotation and will not back out, and if you ever need to replace them they'll come out easily without seizing or galling. Great bike for the money! 5.0 out of 5 stars MARCH 30, 2021 UPDATE, 2ND PURCHASE! By artillerybuff on February 26, 2019 The order stated 3 day shipping and it took 6 days, but more importantly FedEx delivered the box all tore up with bottom flaps wide open and the box of pedals lying on the ground outside of the main carton. The bike suffered several deep scratches that really bummed me out! I decided to live with it as I hate to send things back unless I have to. Other than that the bike is very nice at this price point and would have received 5 stars from me if it wasn't damaged, despite the slow arrival.

The spokes on a standard spoked wheel hold it in tension. If the spokes lose tension, they start to break and the rim will buckle. A Loopwheel is not held in tension by its springs therefore the rim is strong, double-walled, and less likely to suffer from buckling or fracture at the rim.

I spent about 20 minutes out with Sam on the 20″ wheels, coupled up with the Dahon folding bike, and immediately there is something special about them.
Loopwheels' funding campaign runs on Kickstarter through May 15, 2013. Backer packages range from a single front or rear wheel to both wheels to a Dahon folding bike pre-pimped with its own set of 3-speed Loopwheels.

It's unclear at this point whether you'd lose any forward motion energy due to torque flex, but that can be tuned out of the system if required in any case. It's also unclear how much a pair of wheelchair-sized ASWs would cost at this point. We assume they're not cheap compared to a regular rim and tire setup. Here's some annoyingly infomercial-style video comparing regular wheelchair wheels to an ASW setup over curbs and grassy, uneven terrain.
SoftWheel also claims that this movement measurably decrease the energy lost from suspension movement. Their simulated track testing equated these gains to 16.4% extra energy that was not lost in a traditional suspension system. That of course means saving energy for the rider, and results in faster rolling. We’ve seen conceptually similar solutions like the carbon leaf Loop Wheels without damping, and even a smaller amount of suspension built into Gokiso’s hubs, but these Fluent wheels are certainly more tech-heavy.

4: Up hill- this is where i think you may encounter difficulty. since its a climb. assume that you follow case 1, then you should be at least fine here. you have to focus on the ground distance to hub must always be greater than radius of wheel parallel to inclination of climb. (because imagine case 1, if your hub is no longer at the center, you will be lifting your self. in an inclined position. more difficult than lifting in a plane.
Stand back. A performance-tuned dual exhaust system uses two resonance-free pipes to emit an enthralling growl from the massive 5-inch matte-black exhaust tips.

“In the past, if I wanted to go down the sidewalk or over any big bump in a regular wheelchair, I’d feel it a lot on my back, and it would really hurt. You do it a couple of times a day each day, a week, a month, a year – you’re talking about thousands of times,” Cohen told From the Grapevine. “With Acrobat, it's all absorbed into the wheel and not in the back, creating a better sensation when riding a wheelchair.”

The Global Air Cylinder Wheels team has also sent us a bunch of video detailing the advantages of a much smaller scale ASW for wheelchairs. Because of the built-in suspension effect, you'd likely experience more ride comfort, as well as a vastly superior ability to negotiate uneven ground without any of the wheels lifting off and losing stability.

In deep sand and mud conditions, TRX uses a 45/55 initial torque split and calibrates both throttle management and torque distribution to mitigate wheel slip and improve traction.
It is a significant risk factor for those with spinal disorders, increasing the amount of muscle fatigue and potentially damaging connecting nerves. Vibration is also believed to have significant impact on pain, the development of pressure sores, spasticity and general discomfort. It limits the time, distance and surfaces that users will consider for manual chair use.
When off road, use the Vehicle Dynamics page to dial in the optimal steering angle, lock your axles and modulate your transfer case gearing.

There is a lot of research to show that ‘whole body vibration’ is associated with fatigue and lower back pain, increased spasticity (muscle contraction), and an increase in pressure sores and has an impact on bladder control.
After building a PacMac track in its previous video in the Cat Trials series, Caterpillar set up a mock Hot Wheels race track featuring a variety of Cat equipment and life-sized versions of Hot Wheels cars.
The design most likely requires a drum or disc brake since the rim’s position would likely change too much for rim brakes. We’re thinking this could be a fun design for commuter and city bikes where aerodynamics and weight are slightly trumped by comfort, particularly where the streets are a bit rough.

Don’t blink. With eight extra inches of overall width, massive 35-inch tires and a menacing stance, TRX asserts itself as the most muscular truck to ever leave our factory.
It’s one thing to look at the video, but up close they really are a sight to behold – they literally challenge everything you think you know about a spoked bike wheel.
