Thanks for the advice. When I took it for a test tow I loaded my folks into the jeep for added weight to simulate our dogs and cargo. Together they added approx 450lbs...no further comment
the weight and trailer definitely made for noticeable towing but it handled surprisingly well. We took it through the city and up and down approx 30 km of mixed Hwy consisting of a couple of decent hills, rolling hills and some straight aways. It was also a bit windy and we passed a bunch of big rigs.
We went back to the rv dealer again today and after taking a second look around we decided that the X213 is the way to go. We're also playing with the idea of getting into a v8 Cherokee but we'll wait and see how the numbers work.
