Idea for camp trailer / TC storage platform?

I think I already have what you are looking for. I have a trailer made from the back half of a 3/4ton pickup. I don't tow it behind when camping because we usually have a boat or the ATV trailer behind us, but I could. After unloading from the truck I can push the truck box trailer under the camper by hand and then let the camper down onto it. This type of trailer means the jacks don't have to go up/down so far when loading or unloading. I leave the camper jacks down when storing or unhooked from the truck as it is a single axle trailer, but most of the weight is on the trailer and the camper is very stable. I can hook up to the truck and move the camper closer to the house prior to a trip for loading and getting ready for the trip, or to move it out of the way for some project in the shop where it is stored. I would never consider hauling the camper down the road on this trailer, but is perfectly fine around the yard. The best part is I paid $400 for it used, and have no license or ins. costs because it never leaves the yard.
