I have a 17' EggCamper
that weighed 1506 lb from the factory. It was purchased as a "kit" with no
appliances, cabinet doors, toilet/shower (just an open space), water tanks, water heater, water pump, mattress, cushions, dinette table, sink or any of the interior plumbing/wiring. It was essentially a large volume of air surrounded by a fiberglass shell. It did have a group 24 battery
in a box on the tongue (needed to operate the breakaway) but no propane
tanks or tank mounting bracket. The EggCamper
is double wall construction so the weight
of single wall construction could be a bit less.
By my calculations the completed EggCamper
weighs about 1,950 pounds empty (I haven't taken it to the scale yet). As I installed everything I did weight
and balance calculations so I think the aforementioned estimate is pretty accurate. Of course you have to add the weight of all the supplies/water/bedding etc. you plan to take with you.
Bottom line - I don't think you are going to find a fully equipped 17' camper that weighs less than 2,000 lbs ready to hit the road.
Good luck in your search and let the forum know what you find.
