Op, I can speak to this. We had a Winnebago micro Minnie 2108DS. Weighed about 4500 with junk in it. We didn’t travel with full tanks. Wife has a 2016 Limited 4wd Runner. We used an Equalizer hitch and a good smart brake box. For starters, we live in Houston Texas which is very flat. We towed the Winnebago five times maybe 100 miles in each direction. Mostly flat or a few gentle Rollinghills. With a good hitch, it did it and was stable and was not scary. Had to drop down one gear in the transmission to pull it Sport mode. Gas mileage sucked. Cruising speed on the highway was around 60 mph. I would not have wanted to have done it in big Hills. The stability was there and the stopping power and the combination felt very unitized and safe. Never had any issues with wind Or sway. It was grossly underpowered in my opinion For major hauling but local was fine. Again, 60 mph was about all that it wanted. I have a Dodge mega 2500 Cummins. We usually pulled it behind my truck using a standard hitch and no weight distribution. My Dodge would literally pull it faster than anybody ever wanted to run. I usually set the cruise control on about 70. My truck literally did not know it was back there. The forerunner could’ve never achieved 70 and even if it could have, I would not have been comfortable there. If you are doing relatively short pulls and live in a relatively flat area, the forerunner will work for this size of travel trailer. if, however, you want to travel hundreds of miles in any given direction and encounter hills in that type of thing, I would not recommend it. Very big difference between South Texas, Florida and Colorado. two of them are slow and boring and the other one would be perfectly terrifying. By the way, the Winnebago 2108 was the perfect camper for us to start with. We loved it for two years. We ended up in a fifth wheel. Lol
