As long as you are within your limits, I don't see a problem. There are people out there who don't think you should tow a popup with anything less than a diesel dually. I pulled my Kiwi for a couple years with a Sport Trac and had no safety issues. It did put a strain on the tranny, and no doubt my F150 pulled it a lot easier, but I never felt I was endangering my family or anybody else and was always well within the limits of the TV.
Properly adjusted sway control does make a big difference in towing, though. If you ever forget to tighten it up, it won't take long before you notice. Same with the weight distributing bars - adjusted properly, they make a big difference. I know a lot of people say you should adjust them so the nose of the trailer is down, but I don't agree and have always adjusted so the TV and TT make a straight line from the side.
Trailer looks great. Are those two lights in the front by the diamond plate? Mine only has one light and it sure would be nice to have one on the other side to hook up at night. Beautiful spot to camp, too.
