Surveyor Travel Trailer Specifications by Forest River
I see a 25' that is SHIP WT of 4880 lbs. that DOES NOT include propane or battery..so you're over 5k with NOTHING LOADED - like kitchen, betting, bath, chairs, etc.
Yes, your TV has plenty of power...cars in the 70s with smog motors had less power and pulled 'full weight' TT. They also had bigger brakes, full frames, longer WB, more weight themselves, etc.
Add the TT weight, what you load in it, the propane/batt/hitch, your passengers and the empty weight (REAL wt) of your TV and see where you stand compared to GCWR - I'm sure you're over.
Our TT was marketed by FR as 'mid size SUV towable'. And the previous generation explorer was rated at 7500lb towing. The expedition we bought was over on GCWR with that TT...I can't imagine how over the explorer would have been.
Never had a white knuckle experience with it, but compared to our silverado (2500lbs more GCWR, more tow rating, 2 feet more wheelbase) there is NO COMPARISON in towing comfort (and the expy had E rated 10 ply tires vs the jello 4 ply P tires on teh sliverado)
