I don't have the '06, but I have the '07 with automatic transmission. I have towed it over 35,000 miles with no problem, knock on wood. If the '06 is as good you will have not problem. I personally prefer the automatic to a stick shift - only because DW drives it sometimes.

It is what it is, and then it is what you make of it.
