TC off truck

Your TC is a foot longer than mine which is a 1990 Lance..I do not trust the jacks..When I off load mine,I set it on 3 cinder blocks in each corner with a 2X12 across for support..If I was traveling and off loading,I would use those stack jacks with something simple across the front and rear of the floor for support(just incase)..

I have never had a floor issue with it off loaded using it regularly..
