I'm looking into transforming an ordinary 5' x 12' utility trailer with 18" sides into my semi-off-road camping vessel. I'd like to weld/build an approx. 4' x 5' raised platform with an expansion metal bottom at the front of the trailer. I will mount my RTT to this and park (2) 4-wheelers below the platform area. I will also flip the springs over axle to gain some addt'l clearance for the trail. Also will add stabilizer jacks at front & rear. Anyone done this? Any photos? Ideas about this? Thanks...
