A couple years ago I bought a new 7x16 v-nose cargo trailer for hauling gear around. After reading about conversions I decided to work on making it a multi-purpose unit capable of hauling cargo, short term camping, and driving into a field to set duck/goose decoys for hunting. That means everything camping wise inside would have to be removeable so I could haul cargo, I'd need the creature comfort infrastructure installed and ready to go, and I'd nee enough ground clearance for field work. Not really what folks are usually going for in a conversion I suppose.
Still have a long way ways to go, but now the major mechanical stuff is done, which was out of my league, and that clears the way for me to start the interior modifications. This is a 7x16 trailer with a 2 ft v-nose, and has an interior height of 7' 3". Now has 7000 lb straight axles (stock was 3500), 5600 lb springs, 8 lug 16" wheels with load range E tires, load leveling hitch, electric tongue jack, dual 6 volt batteries in a lockable box (batteries charge when hooked to shore power or to the tow vehicle), sliding window in the walk door, a sliding window on each wall, 30 amp RV hook up with electrical panel and 12 volt converter, overhead vent with 3 speed Fantastic fan, 1 1/2" thick floor, 3/4" plywood walls 1/4" plywood ceiling, fully insulated walls and ceiling with rigid foam board, folding entry steps, folding hand rail, and 4 interior electrical outlets. Also now has 18" of ground clearance for the lower deck. And yes, I need to build the cabinet to properly mount the electrical panel. Right now it's packed to the gills with boxes to go from California to Montana, and it's maiden voyage for camping will be the end of July. By then I hope to have the cabinet built for the electrical panel and the rear bed system in place.
Always open to suggestions.
