I have been towing with a dolly for 20 years or more with out ever having a problem. Since we change cars often as long as it is a front wheel drive we are good to go. In that time I have had 3 dollys. First had brakes, never again, I kept it exactly 1 month and got one without brakes. Kept that one many years and many cars and wore out 3 sets of tires. Got a new one which I still have and its on its 2nd set of tires and many more cars. Our main towed car now is a Smart car and we have a front wheel only CRV Honda and a Toyota Camry. Did have a class C when we first started but have had Diesel pushers since 1997. A good dolly today is about $1500 and you can find them on Craigs list for less sometimes. Get your info from someone that has done it, not read about it.
