i plow tight driveways in tree infested housing developements. so it is very important to have a serious rear bumper. i'm planning my next plow rig and am wondering if anyone has any ideas. i have one idea to start, taking an idea from camper extension bumpers. by mounting 2 reciever hitches with open backs at both frame rails then building a 6x6 1/4" square tube bumper with 2" recievers to slide into the mount and be extendable when plowing. it could also act as a ballast weight in the lighter plow vehical (JEEP)
