About how fast were you going? I'm doing a 1,400 mile move with the same U-Haul trailer. California speed limit is 55mph while towing which I'm hoping gets me at least ~450whpm.
Also, how did you handle overnight rests? The trailer coupler doesn't have a lock which I'm a little nervous about. Thanks!
I kept it between 55 and 70mph. Pretty much just went the speed limit and stuck to the back roads. If you are doing your trip in warmer months you should be fine.
Overnight I was concerned about theft but there is always sentry mode and being selective on where you park. I only had one overnight stop on the trip. Just make sure you lock the trailer door.
