Leveling with dual wheels

Cloud Driver makes a good point about leveling with the front tires if possible. Then there is no difference from a true Class B. I'm just looking at unexpected complications of stepping up in size. Giving up mobility is the main issue, you can't just whip off the highway into a Taco Bell or park right in town.

I've been through a few cycles on this issue, here's the one before my current solution:



And the storage solution:


Storage location:


I've since replaced the 2x6s with old 3/4" plywood, cut into 11x18 rectangles. I carry about 7 or 8 of these, and a couple 8x8s if I have a side-to-side incline. The plywood has held up well considering the amount of use... including when I had the entire MH setting on jack stands:



These store in the same container as did the 2x6 blocks.

I bought a rubber horse stall mat and cut it up into pieces. They stack great, don't compress and have great traction. A 4'X6' mat was about $50. Lynx blocks are 8" square. I recall that I cut most pieces 8"X10", and a few 8"X8". That allowed me to combine them in stacks that could give me lots of choices to level. At max I can do about 4.5" under all three tires of one side. The mat is tough to cut, but cheaper than Lynx and works awesome. They are heavy, though.

I "Lync Block" under the pair unless I am short on blocks, and rest easy over the decision. There are curbs where if parked properly, the outer tire will be suspended in the air over the rain gutter. This is no different. Avoid it if possible, but don't sweat it if you can't.

I think we may be searching for a solution for which there is no known problem(the government does this a lot). :B About half of the sites we occupy require some sort of leveling but I have yet to ever need more than two yellow Leggo blocks. I do place them under both of the wheels for more even support but aside from actually bending over to slide the block(s) under the inside wheel it does not involve much effort. Our bag of blocks contains 8 and that has always been more than enough. :C

I have a set of HWH semi-automatic levelers. I sit in the driver's seat, push the "on" button and they pivot to the vertical position. Then just push whatever light is lit until they all go off. Then push the "off" button. They move in pairs. Front two, back two, left two or right two to keep the frame from twisting. Worth every penny when its raining.

Before parking we get out and scout the site. Can usually find an area to park without blocks. sometimes back in, sometimes pull in frontwise. Sometimes just find another site. Last year on a five week 5200 mile trip in the Rockies, staying mostly at NFS primitive campsites we never used blocks once. Once in a pinch several years ago we did use blocks on the duals, only blocked one wheel. I didn't feel sitting on one rear dual tire for 1/2 a day not moving would be a problem. It wasn't.

We also use Lynx Levelers. We carry three bags of 10.

IMO the Tri-Leveler is a bad solution for leveling. The flat areas on each step are way too short to support the normal road contact area of the tire. This puts extra stress on the portion of the tire that is resting on the step. The pictures on the Camco web site dramatically show this poor support, with half of the normal tire contact area hanging off the step. The first picture also shows the very high stress point where the tire is crushed at the edge of the step. The narrow contact area at the edge is carrying nearly the entire load on the tire, which could cause damage to the tire cords.

Lynx levelers also have an issue with proper support of the full tire contact patch, as there is a large recessed area in the center of the block that provides no support. I made some 1/2" plywood inserts to fill this gap and properly support the tire contact area. I assume that the Lynx Caps would do the same.
