I use a 2 foot level on the floor. I don't trust those cheap stick ons. as for your springe check the dimensions as well as the suspension. look for cracked or broken parts and do it on a level (preferably a concrete slab) surface. I am currently planning on putting a wet suspension kit under my 3912. im not taking chances. especially since lippert/ keystone uses plastic bushings on their springs
