Hello everybody! Its my first time posting, so I hope I'm doing this correctly. i have read these posts for a few years now and found out quite a bit of useful information. What a great forum! Anyways, I'm planning a trip from Columbus,Ohio to Lancaster, Pa. next year. I'll be pulling a 31' travel trailer there and back in august. truck and trailer combined weight with gear is around 14000#. Trailer itself is 6500#. google says to take I-70/I-76 east most of the way. What I'm wondering is how hilly or mountainous is this route and should I even be thinking about pulling this much weight through this route? I'm pulling with an '07 ram 1500 4x4 with 17 inch wheels and stock size tires. My rearend gearing is the 3:92 I'm pretty sure of. I have also installed a 12"x14" tranny cooler inline with the stock tranny cooler. The truck also has the tow package on it. My tranny temp gauge runs around 170-180 degrees when i pull the tt on flat terrain. My truck also has around 130,000 miles on it. Any help and suggestions would be appreciated and thanks much in advance gentlemen!
