I never turn around while backing either but I don't have a rear camera either. I've just always used my side mirrors for backing up even in cars just a habit I guess.

You have to keep in mind the weight of a 32" tire and wheel and I'm sure you will want to mount a gas can so that's another 50LBS. So you will have over a 100LBS to hold up with what ever you build. Now extend the weight out past its support pieces meaning the weight is not resting on top of its main support its extended out past that which will increase the stress of holding the weight up. Then consider pot holes and dips in the road and that will add even more stress. Now go off road and bounce around drive down some wash board roads and that thing is getting abused pretty good. Also consider maybe getting it hung up or hitting off road as you depart an obstacle it will need to stand up to that as well. It will need to be pretty solid not to vibrate and make noise back there which would drive most of insane. I'm not saying it can't be done because it can, I'm just making sure you're considering the weight and stress this will produce. I would tie it in at least in three places. The two frame rails and the tow receiver as supports for this and anywhere else there is solid frame to help support this. Then when all is done probably install a rear skid plate that would protect it and protect the frame rails back there as well. I have everything I need to build this except a welder which I need to stop procrastinating and just go purchase one. I might just chill with the mods on the jeep for awhile and use the money to buy some more tools like a welder and a pipe bender and stuff.
