Tow Travel Trailer with Truck Gate Open? Anyone done this?

It all depends on the trailer in question, and how close it is to the tailgate. Only way to really find out is to hook up, drop the tailgate, and check. I did it with a popup camper, but had to relocate the tongue jack to the side so I could pivot it out of the way.

Be sure to use a long piece of channel iron to distribute the load, otherwise you have a lot of weight sitting right on the tailgate. Probably would be fine, but why push your luck.
