What are you guys using for jack stands on your vans? I have a Roadtrek Chevy Express 3500 which has underslung cargo so the typical 3.5 ton jack stands are unable to reach up to the frame as they max out at 20". They work fine on the rear axle but that's about it. I'm looking at 12 ton jack stands which are good for 20" through 30" and should have enough reach to get past the cargo up to the frame.
As for a jack, I have the ProEagle 3 ton offroad jack.
I don't have a lot of use on the jack but so far so good. You would still need a low-profile jack for doing suspension work where you need to lift up control arms with limited space, etc. They make an extremely expensive carrier for it which would be handy.

As for a jack, I have the ProEagle 3 ton offroad jack.
