When we purchased our TT we bought it with the notion of pulling it behind the wife's Hyundai Santa Fe which was rated at 5000# towing capacity so we bought a 20' TT 23' with tongue that when fully loaded would be well under the 5000# rating. The camper sales hooked everything up and we left on our way back home. It didn't seem to bad to tow and we took things pretty easy. The second or third time I towed the TT behind the Santa Fe we were driving with quite a bit of side wind and it was pretty scary the whole trip back home, fortunately we were less than 150 miles to travel. I had white knuckles by the time we got home and the wife was a nervous wreck. I took the TT to another camper dealer a few days later and asked them to check the WDH system, I had my concerns about how they started things out when the guy that was supposed to check things out had to leave and told someone else how to go about it and then he left. The guy that was checking things out and making adjustments had a few ideas of his own how to set things up. It still did not tow very good afterwards maybe as bad or worse than before.
It wasn't long before we purchased our 2016 F150 w/2.7 crew cab 4x4. After hooking up the TT to it I went to an empty flat level parking lot along with my tape measure and instructions as to how to set up the hitch. I spent maybe 1 1/2-2 hours there getting everything set up including adjusting the ball height etc. It has always pulled like a dream, if I recall correctly when I have the trailer hooked up to the pickup that my pickup is pretty much level, it might squat down 1/4-1/2" on the rear fenders don't recall for sure.
I have often thought about hooking back up to the Santa Fe and setting the WDH back up to it and adjusting just to see how it works but laziness has kept me from it LOL. Also I don't have any reason to tow the TT behind the Santa Fe since I have the F150. I am curious as to what your max loaded weight of your travel trailer is supposed to be as you might be pushing towards the top of the towing capacity of the 2.7. I had to take my TT back to where I bought it for warranty repairs and I asked them to see what they could do as far as the tank gauge system as it was not working correctly. I thought after we left there the TT seemed to be towing harder than usual but we weren't going very far and thought maybe I was bucking a head wind. After getting to where we were going to spend the night I found out that all three of my tanks were full. Not long afterwards I noticed I was getting some tire wear and had the alignment corrected. I have always thought with the added weight of having all three tanks full might have knocked the alignment out as the three tanks being full would have increased the weight about 750#.
