carld, nice list. Too much effort for me. I just took the loaded camper to the truck scales!
cdbrow, My older Ranger II camper has the 1.9cf fridge and a smaller 12 gal water tank. As I posed earlier, if I am going to camp near water ( 90%) I only carry a few gallons and pump stream water from a collapsible bucket through a ceramic filter as needed. My tankless water heater weighs 11lbs and works great. I am almost always alone. I carry tools, but just the minimum. Sockets, wrenches screw drivers, etc. I built the truck so I pretty much know what I need to fix it if necessary. The truck is turbocharged so I carry 2 extra quarts of engine oil. I carry a tow strap and the hooks and rings mounted on the truck frame. I do not have a winch on this rig, but may add a small one on a receiver so I can use it fore or aft if needed. I take mostly freeze dried foods and no liquid drinks. Aluminum and titanium cookware. Maybe 3gals propane. I house battery wired through a constant duty solenoid with no monitors, etc. No porta potti, no chairs, No camper jacks.The only place I can think of to reduce weight on my rig is the camper steps. I have a modified set of Brophy steps that fold up. A plastic step stool would be lighter. I think the older units were much lighter. I remember the specs were something like 595lbs with an ice box. I think the newer models are heavier than advertised.
In contrast, I also have a 1952 Willy's Station Wagon with a small camp trailer that I use for extended hunting trips with wall tent, wood burning stove, 3 way ice chest, table, chair, 8000lb PTO winch, Pull Pal, Hi Lift, etc that weighs in at almost 6800 lbs.
