wnjj- thank you for the response. The actual TW is probably over the manufacture rating. It's a 12' trailer w/ a 12' utv so it's snug. I used to bring it up the ramps in reverse (where it weighs the most) and towed great and straight both in my F150 & F250 ( it barely lowers the suspension on my F-150). To make this all work I'm going to be driving it forward to lower tongue weight
UTV has a dryweight of 1,670 LBS (based on rumors 600-700 lbs in front and 900 lbs in rear). I just assume I'm close to the trailer gross. BTW: 12' trailers to haul around RZRs are pretty common. Ultimately decided I would take the risk with a single axle. I do have sensors on wheels for PSI and blowout monitoring.
I didn't think about extending the front of the trailer. Not bad. I'm concerned about altering the trailer though and at that possible price point, maybe I should just buy the 2.5" hitch and the Reese 6K lbs/ 600 TW 24" extension so that I can more safely meet the ratings.
