Cobos,
If backing down a boat ramp is the only reason you want the camper off, do yourself a favor and leave it on. And leave the jacks at home. Of course, I am the self-proclaimed "King of Jacks Off" so take it with a grain of salt. Install a front class III hitch on the truck and carefully reattach the trailer to the front. Turn the trailer around while in the holding area and make the switch. You can see exactly what you are doing, since its a front row seat, and it is easy and slick to marshall the trailer down the ramp. If you have 2WD, the weight of the TC acts as a traction enhancer while backing up the ramp. Be sure to use a spotter when coming back up the ramp to the flat. Pre position the tongue height to just clears the front ball. You will surprised how easy this is, once you have a little practice. The only caveat is to have a couple chocks for the trailer wheels while it's sitting there on its tongue wheel waiting up on the flat for the aft to fore switch. Most boat ramp parking areas are completely flat, for a reason, but I like the belt and suspenders aspect of chocks.
This will save you a lot worry about wind; disconnecting the power and tie downs; kids playing under the off-loaded TC; and re-loading the TC.
