We debated the two and went with the tt. We have a cap on the truck that locks. We added a sliding bed so we could easily reach the stuff in front. We would never switch it for a 5er. We have no problem with sway and hooking up is easy with a back up camera. We carry a lot of stuff in our truck bed such as generator, compressor, tools, because we might need them when we are off road - we feel they are more secure with us than back at a campground or remote boondocking spot. And, if worse came to worse, we could always sleep in the bed of the truck (we are prepared for that, too). I think it all really depends on how one uses their truck when not hooked up to whatever it is towing.
