Thanks for some of this recent feedback. I've pulled many trailers with my truck and driven semis, but this is only my 2nd TT I've towed. As I've mentioned the first was always smooth and easy and this is a PITA. This is some of the feedback I was looking for in the beginning - different things to look for besides my tongue weight. (Not saying that isn't important, but other issues will exist that I've never had to worry about before that I need to check/play around with). Thanks again and keep any new feedback coming. It will help me to find the best all around adjustments and hopefully help others in the same situation. 36' of trailer and around 10000 lbs plus my truck is a lot to have tossed around an interstate and I don't want to be the cause of the wreck.
