tow dolly costs less than a good 4 down system, I own multiple fwd cars and tow any of them, I only stay in nice rv parks with good pull thru sites, I don't have to modify my toad, surge breaks are simple no electrical hook ups other than lights, hitch on my toad allows me to easily move the dolly if I want to, tilt wheel on dolly tongue makes the dolly easy to maneuver or raise or lower. attaching straps is easy with a little practice, 5 years towing without a single problem, won't have to modify the next car I buy, won't have to modify the next MH either either way you go a toad of any kind is one more thing to bother with but a necessary evil, either way works so personal choice dolly costs less and has more flexible use, 4 down is physically easier especially for older folks or those with physical limitations I am 73 and no prob loading on first try just pull up to ramps get out and check alignment, correct if off slightly, then drive on, easy peasy, I have a master tow but others are good too
