with the exhaust heres another idea. if your truck is a daily driver as well and you dont want to have your exhaust pipe sticking up over your cab you can make a removeable section that you bolt on when you go offroading. example:
say on my suburban i had a roof rack, i could weld a tab onto the passanger side of it, towards the rear of the truck that i could bolt a piece of exhaust tubing to. that exhaust tube would also be connected to my regular exhaust pipe that exits behind my right rear wheel, and just have a regular exhaust clamp connecting the normal exhaust to the extension.
