Hello, I'd like to welcome you to FiberglassRV. If I may ask... who am I speaking with? "M" seems so impersonal and you'll find we're a kind, friendly and helpful bunch.
Ditto to getting it weighed. And, removing the furnace
, stove and propane wouldn't reduce the weight as much as you'd think... maybe 200 lbs if you're lucky. Besides, you'll just replace that with a different stove, etc. so you can cook outside. Sorta like robbing Peter to pay Paul. Remember, it's not just the towing weight limit, but the tow vehicle's gross combination weight rating as well. That includes occupants, gear and everything else.
