U-Haul would not rent me a tow-dolly saying that the car I was towing "would not fit". (I think that was BS, but it don't matter as they would not rent me one.) The cheapest U-Haul trailer was $450+tax.
I decided that if I was going to spend that much money, I would first go by the local trailer dealer and see how much a dolly cost. I ended up with a Tow-Master 77 with electric brakes for just under $1k+tax. I made the trip without any troubles yesterday (Saturday).
I have towed a dolly only once before and although they had a non-brake unit for $200 lower (an old, but new unit that had sit outside for a while), I decided that I wanted the electric brake unit because I remember how much stopping can be affected with 3500# behind me. Considering that I was going to have to spend $450 for the U-Haul trailer, I now have a dolly that only cost me $550. (At least that is what I told the wife.
) I have a place to store it, but maybe I will put it on ebay and see if I can get my money back since the list price for the dolly was about $1500.
