nope, haven't towed anything.. i doubt i ever will.
I/and so were the people who drove it, where impressed how well it pulled the 40" tires i had on yesterday. That will be the biggest comparison to pulling/caring/moving more weight than normal.
are you happy with your swap? Ive been getting between 17-20 mpg driving it on 35's and 5.29's in the mountains where i live. its got great power, runs awesome, and is much easier to access things in the engine bay. VERY happy with the swap, only downside is going to be seeing the ref.
