help with chassis build plz

I am going to build a single seat ATV in a rock bouncer/crawler style. I am pretty sure most OME side-by-sides are built using 1.750 tubing (don’t know the wall thickness they use). I want to use either 1" 0.095/.120 or 1.250 0.083/0.095/.120 <<one of the three DOM steel tubing. Several reasons I want to use these tube sizes is (1) I already have dies for those sizes and don’t want to spend $$$ for new dies.(2) I can get a real good deal one the tube per foot. Something I would be doing that stock OEM manufactures don’t do is I’ll be gusseting all the critical stress area. If I go with the 1" .083 I would build the lower part of the chassis with a double frame. I know I said the chassis would be like those high dollar rock bounce style, but in reality once built it would see VERY little if any rock bouncing/crawling & if it does it would be the easy trails. THANKS!!
