GCWR & GVWR question


I apologize for asking a stupid question whose answer I should know. Were about to drive 500 miles to check out a travel trailer we may buy and I want to make sure Im not overlooking something when it comes to weight.

Our Truck (2012 Ram 3500 Crew Cab Long Bed SRW 3.73):
GVWR: 10,100#
Base Weight: 7,000#
GCWR: 21,000#

Travel Trailer:
GVWR: 11,700#
Base Weight: 8,225#

Suppose we put 1,500# of stuff (people, cargo, fuel) in the truck and 2,000# of stuff in the trailer, then we have the truck at 8,500# and the trailer at 10,225# for a total of 18,725#, well below the 21,000# GCWR of the truck. (With an extra 1,534# to spare for the pin weight on the truck, keeping it below the trucks GCWR.)

Are we ok? I ask because even though the actual weight of the whole assembly will be below the GCWR of the truck, the sum of the GVWRs of the truck and trailer is greater than the GCWR.

If the loaded truck weighs 8,500 lbs and the loaded trailer weighs 10,225 lbs (using your numbers), then the trailer's hitch weight will be about 12% or so of the total weight if it's loaded properly. 12% x 10,225 = 1,227 lbs that the truck will have to carry as hitch weight. 8,500 + 1,227 = 9,727 lbs which is less than your truck's 10,100 lb GVWR. Looks like you should be OK, but you might want to weigh it once you get everything loaded just to be sure that your axle weights are OK as well.

Your truck can pull a trailer weighing up to 10,900 lb including hitch weight

"Pull" yes, but "haul" the hitch weight along with other cargo such as passengers and toolbox without being overloaded, maybe not.

Properly loaded TTs have hitch weight of around 12 to 15 percent of gross trailer weight. Use 15% for a better estimate if you don't want to be overloaded. My TT has a hitch weight slightly over 15 percent. I used 12% for estimating the max trailer weight I could tow without being overloaded, and wound up slightly overloaded for a 4,000-mile trip.
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 3.5L EcoBoost SuperCrew.
