3.7 Towing
What size Travel Trailer? Need more info to really help. There are certainly better engines for towing but if the 3.7 is what you have then you can try to make it work.
Don't have a TT, but do tow a 22' enclosed car trailer weighing 7800# fully loaded. Have towed all over the Midwest and the EB does fine, no complaints. Had been considering a 250 w/6.7 power stroke, but after talking to other 150 owners towing enclosed car trailers, I was convinced the 150 EB would meet my needs.
