On paper looks like it will work. You'll need to watch the payload limit of the enclave. So while it is listed as being able to pulling 4500# it's the weight on the axles you have to watch.
There will be a sticker on the door that list GVWR - max weight that enclave can be. In addition it will list the max weights that can be on each axle.
Once you put people, gas, gear and trailer tongue weight on the vehicle it's not uncommon to go over one these limits well before you hit max towing capacity.
It's important to weight your vehicle and trailer a Cat scale. This will let you know if you need to shift gear from TV to TT or if you need to move stuff in the TT to adjust the tongue weight. Here's a good thread on weighing your setup http://www.jaycoowners.com/forums/f3...v-tt-3871.html
