jerrym - Wow, I knew Big Foot would be expensive, but that is way out of my league, too. Did some more checking, and you might want to look at some of the stabilizer jacks made by BAL. They are a division of Norco Industries, and web site is
www.norcoind.com If you just want stabilizers, and not necessarily levelers, then the cost goes way down. I see some C jacks and some telescoping stabs on their site that might do for your situation. Some go as high as 5,000#, which might be enough for your Class C. I think it might be worth a look, anyhow.
