at 1st we rented, fine for us when visiting in-laws etc but picking up the car can be problematic....getting to the rental and returning it is a bit of a pain.
finally bit the bullet on a '12 jeep wrangler (picked up a blue-ox aventa aluminum tow bar & base plates for 250 bucks off craigslist)...towing the jeep cost us less than a 1/4 mpg if that, it tows well and takes seconds to connect & drop...we don't even know the thing is back there.
now that we have the toad i tow it even when we don't thing we'll need it....i call it cheap insurance....if we break down i can alway run for parts or send the wife/kids ahead w/out me.
if you get a toad make certain you put a tire pressure monitoring system on it....if you have a tire issue on the toad you'll likely never even know it otherwise.
