Tow Vehicle - Dual tires in back or single? Which is best?

If you are towing a TT then you do not need the dually. Also I have towed six different trailers over the years with 2WD only and never once would have needed 4WD. I would not take my trailer anywhere that would require 4WD to get there and out.

I didn't have a choice as 4x4 was pretty necessary to park it at the house. Is it something against 4wd trucks or "rustic" campgrounds?

Anyhow, I would hold out for a 4wd system and the only downsides to duallies are pretty much economic.
