Kudos to your decision to try things out with a Uhaul car transport trailer. They will give you a chance to try before you buy. d
The Uhaul transport are a beefy-strong trailer for just about anything you would want to tow on it... and they are pretty heavy in comparison to an aluminum trailer you might consider buying. Our trailer is rated 10k and is fine to pull with our Seneca, our previous motorhome pulled it too, but we had some opportunities with cooling that 400 Chevy chassis and towing hills in summer.
That said, Try things out with the Uhaul trailer. Take it to a Scale and get your weights with the trailer loaded and enjoy the freedom of being able to back up anytime, anywhere!
