Something doesn’t sound right, maybe the specs. changed from a 2013 to a 2014? Or since I have a lot of options this will affect the weights.
I have the complete opposite problem. Ended up buying a 1 ton truck.
I have a 2014 275ULSBS and the specs and the brochure lists a base weight for the 275 of 7843 LBS. and a hitch weight of 1129 LBS. I have a lot of options so my trailer weight is above 8,000 Lbs.
I have a generator installed under the front bed and a battery box on the rack with three batteries. But the on board fuel station is located behind the axels. With a full tank of fuel (24.6 Gal, even though the specs. say 30 Gal)
My tongue weight with the trail disconnected and one battery with the LP tanks filled, is about 1450 LBS. With three batteries the tongue weight is about 1650 Lbs. (I have this written down at home, but I am at the office right now so this may not be exact). So I have to add four containers of water in the back (24 Gal at 200 Lbs.) and this drops the weight about 100LBS. Adding my coolers and ATV at 650 Lbs. my tongue weight doesn’t get below about 1350 Lbs.
Do you have an on board fuel station? Is it full? Are your LP tanks full? IIs you spare tire mounted up front?
You may want to add some batteries up front.
