I didn't see what brake controller you are using? A proportional controller like the Prodigy will make a WORLD of difference when braking.
First thing I did when reading your post was look at your location. I am in PA, you are quite a distance from here.
The things you describe are very common issues for the inexperienced towing person. Not to worry, though. An experienced person can look at your setup and in about 10 minutes suggest changes to pretty much eliminate the troubles you had.
What brand and model tire do you have on your TV? What is the max inflation on them, and what are you running in them?
Huge discussions all the time about using the max pressure on the tire vs the vehicle's door frame. The vehicle doesn't have any way of knowing what the construction or brand or style of tire you are running, so it cannot possibly be the final say on inflation ;)
Another hint: If your tires have "P" in the numbers, they aren't going to be good for towing near the top end of its capacity. Another easy fix ;)
Do you know anyone locally who has had a camper for a while? They probably have some good input ;)
