I do a similar thing. I use the frame and adjust the trailer to get as level as possible front to rear and side to side. I also check at multiple places because these lightweight frames twist easily. Once leveled, I install levels at opposite corners so that I can see any twist. The cheap levels can be stuck on only after replacing the junk foam with VHB tape from 3M.

I have the same levels from Camco. They lasted 1 year and now the liquid is no longer green - got sun bleached. :( It's clear.
