My 2012 Hawk has the furnace, 2 small propane tanks, no hot water tank or heater, ice box (they screwed up there cuz I ordered it with a cabinet built there, not the ice box), a 110V AC air conditioning unit (that requires a bit more aluminum strut bracing built in), a single vent with Fantastic Fan (which I easily upgraded to the 14-speed rain-sensitive and remote-controlled model), spare battery and controller, screen door, and roll-over couch set-up. I took out the bed cushions and use Thermarest 3" air-pads instead (more comfortable). Scaled the truck with no water in the camper tank (looking to take this out as well, I have no use for it). Came out to be 1225 lbs. That was well over what the 4WC data plate and the options weight list I requested claim.
Since then I have removed the rollover couch and cabinets on the passenger side for more cabin room. If we want to sit inside, we use folding camp chairs. Between always moving the cushions and the top-hinged lids on the cabinets, they were frustrating to use and made it difficult for an old fart like me to get to the turnbuckles.
Camper is on a 2011 F-150 with 5.0L gasser, all stock except for some AirRide bags and a front-located Bambi-bumper dent. Getting Hellwig Pro-Series 2500# spring assists installed on Monday to see if they reduce sway and to make me feel better about being over a mite over GVWR. The truck runs like the bed is empty and I got an honest 15.8 MPG on a 4800 mile trip from KC to Glacier, Yellowstone and back despite the damn ever-present Kansas cross- and headwinds. New E-rated tires are next, after the tax man cometh. About that time, I'll also try to convince the wife to let me get rid of the dumb chrome stepbars it came with.
