I don't disagree with Chum Lee.
At the same time I need to say that my standard automotive tools apply well at home concerning our E350 motor home with only two special considerations.
1) Have a floor jack rated strong enough to lift any corner of your rig.
2) Have jack stands that are rated for that same weight.
Of coarse it is wise to have extra margin. If you need a 3 ton floor jack, buy a 4 ton, and so on with jack stands.
When I need to lift a rear corner, I use the 6 ton bottle jack that came with the rig. When I need to lift my 3200 pound front, I use my 2-1/4 ton (4500 lb) rolling floor jack. I have two pairs of jack stands. I would not use the one pair because they are "lighter duty" with a small base.
