Thanks for the replies! I appreciate it. I was under a bit of time crunch, since we needed to pick up our trailer this morning, so i just had the RV dealer install it. Thing is, once he installed & tested it, they found that it didn't have the "grab" that it should have. So I had them install one that they had. And the Tekonsha they ended up putting in was a few bucks cheaper than the Reese I had brought anyway. So I returned the Reese to Tractor Supply and got my $100 back. Drove it the 35 miles home, and had no problems. Another thing I did was to use cruise control for a bit while in tow mode. From the tiny bucket of knowledge I have in my head, it didn't seem like it would hurt anything. But maybe there's something I'm missing...? One downside is that it can be easy to rely on cruise too much, and therefore could get dangerous when towing the trailer.
