The only tubing I would recommend using for a chassis build is A513 DOM. 3" is available in .065" wall. I would look for a shop that has a mandrel bender capable of doing that size. With that said I would find the shop BEFORE I buy the material. Wall thickness does come into play when bending tubing, probably more so when using the Pro-Tools or JD2 style follow benders then with a mandrel style, but the wall thickness can be too thin for a follow style bender to do it's job without kinking the tube. You may have to bump up to .083 wall to have it bent.
The other option is to go with a more common size tube. 1 3/4 x .095 wall would build a stout chassis, it is used every day in race car construction and any competent hot rod shop should be able to bend this for you.
