Yes U Haul does rent tow dollies just like they rent the trucks and trailers.
Renting a Tow Dolly from U Haul costs around $45.00 to $60.00 per day depending on the location and where you pick up the tow dolly and drop it off at.
If you plan to use the Tow Dolly for a week it can cost as much as $315.00 to $400.00 for a week long use of the Tow Dolly rental from U Haul.
If you need to use a Tow Dolly more often then buying your own Tow Dolly can be worth it and much cheaper than constantly renting a Tow Dolly.
And you have it ready for use at anytime.
I used to rent Tow Dollies from U Haul when needed but I saved up money and just bought my own Tow Dolly which was well worth the cost.
I actually even rent my own Tow Dolly out to some people around my neighborhood when they need a Tow Dolly.
I rent my Tow Dolly at around $30.00 per day which is cheaper than U Haul so that has helped pay for the Tow Dolly as well.
