is it possiable? i thought i would make a thing-a-majiger to come out of the reciever hitch to hold the backend of this thing up. i wanted to keep the cost down and was thinking of building it out of wood. would i need air bags. also the vehicle does have a 8" lift on 37" tires. also the two sleds i would carry are a nitro and a rx1. any suggestions on how you would do it?
