flat towing - whos done it? pros and cons

I agree with buying a trailer. The longer you own it, the more often you use it, it will pay for itself. Just like a pickup, once you have one, you'll wonder how you did without. (It does help if you have room to park it, though it can still be used as a parking space. If used as a parking space, make sure it can't be stolen, along with the car on it, lol)
The only problem is the recent "inflation" in prices.
