BlackBoost

Wasn't aware of that. My 2.7 EcoBoost has the 3.73 gears but I do have the payload package so that makes sense.

for me, HD is great for additional GVWR and rear axle capacity. After many years towing and weighing travel trailers, I found that if I have appreciable hitch weight, plus passengers and/or gear, you may be surprised to find yourself above GVWR and rear Axle ratings.

would suggest that you weigh the rig (or similar one with similar options, with the trailer

good luck
