Towing Advice - Dakota and Coachman Apex/Nano

I had your exact truck 3 years ago when my wife and I bought our 19 foot shadow cruiser. except it was a 2001. (loved that truck). Our dry weight for our trailer is 3400 lbs and hitch weight at 340. Loaded on scales the one time we checked was 4100. (Full 36 gallons of water plus "stuff") The truck pulled the trailer just fine. We live in the mountains of Utah and the only timeI I stressed was pulling up long mountain passes where it would approach 4000rpm and be at about 45 mph. You knew you were towing a trailer! That being said its at 7000 feet and 6% grade. I never had any sway with a very good anti sway and WDH installed. I think your truck will do just fine. I will say after the first year we upgraded to a 2013 Dodge 1500 5.7 hemi and I have to check the rear view mirror to see if the trailer is behind me.
