I don't know about the other guys on your "trail riders", but my truck has never lagged while hauling a 36' 4 horse trailer loaded with a massive 18 hand 1200 lb Canadian Warmblood. I have 3 others, mares, one 16 hands, one 17 hands, and another 17.3. It lasted on a trip from a small town just right over the Mexican border in Texas, to Cherokee Co. Alabama. I love my truck!

My opinion is go with the Dodge.
Just my two cents though.
