Sounds like the confusion is a flat deck equipment trailer vs a camper used as a residence. My 33'x96" 5er was 10,000lbs empty and 16,000(almost 500lbs /foot loaded) going down the road with a family of 3's possessions for 23,000 gross . A 26'x250lbs /foot=6500lbs. Add some for the wide body version. For comparison a U-Haul Auto transport (car trailers) was 1950lbs for the old orange and 2200lbs for the newer 4" wider galvanized (info is dated circa 2000)with a 350lbs tongue weight for both. Was a real pain in the a $$ to take off/put on when the jack was damaged. As for deck length they could bearly hold a 130" wheel base, full size extended cab long bed was to long to fit.
Sparkeys mall or is it Sparkey small
I like the idea of a side opening(gull wing )Aero Tonto cover. The only problem I have with it is running with a load taller than the Tonto with it hinged at the top of the cab I can put a full 1ton pallet of wood pellets in without having to remove the Tonto.
For some reason the sight uploaded the pic upside-down[edit fixed].
Part of the design consept was to use the cover as a wing to divert air around the nose of a trailer. By blocking the cap in an open position.
I would advise agenst EOC (engine off costing) unless your transmission is rated for flat towing with the trans in neutral (not the t-case) . Reason: no lubricant engine off = front pump off. This practice is fine with a manual transmission.
Grill block looks like a good prototype. If more heat can be handled block the 2 holes in the bumper. They are for extra cooling something that was introduced on the 2nd gen Cummins. A good tell if you can handle more blockage would be the %of lockup on the electrical fan cluch. A quick Google showed the macanical bi-metal on/off and the electrical variable lock up for 99 v10, so you'll have to check it out. If the fan is not engaging it can handle more... if it is thean back off a few sq" at a time to get it to not engage.
Congratulations on the inside work.nice in winter but can be hell in summer.
