18' 69
Caravel with 99 Honda Odyssey. I have been towing this trailer all summer. The issues I have encountered are:
Check the sidewall stifness of your tires. I notice my tires wearing out very quickly with the extra weight of the trailer. Once the new tires were installed everything is much better. I run airbags in the back of the Odyssey and a Reese Straight line hitch. I have yet to encounter any sway or braking issues. I also have a Tekonsha P3 controller which does a very good job for us. I am also running synthetic oil in the trany along with the cooler.
We live in BC Canada and have done many mountain roads. Good luck with your trailer hunt!
