How Many Miles Before Towing with New Ram 3500

Thanks for all the responses, guys. I really appreciate it.

I will try to get the trailer home with my Ford and then run the Ram for a few miles before towing. It is probably not the best idea to try to get the trailer hooked up to an unfamiliar truck and hitch in a dark barn anyway (sounds like trouble, doesn't it????).

In the worst case scenario where I do get the Ram before picking up the trailer I will be super careful hooking it up and go real easy on it towing home.
