You can't tow because it's not 4wd... Ok, Ok, just when I think I've heard everything somebody comes out with another clueless claim and tries to pass it on to someone like you and you pass it on to us. Thanks for the laugh.
Whoever told you that.. DO NOT BUY FROM HIM
As the other poster said. Check out the Remco Towing site, there they have lists of vehicles by manafacturer (They are spreadsheets) and you simply find your vehicle and it will say one of the following
Towable, no mods
Towable, remove fuse
Towable, With Lube Pump
Towable, With Axel Lock
Towable, With Drive Shaft disconnect
And in a very very few cases "Can not be towed safely"
But that last class is very small. Many vehicles fall into two or 3 of the above groups. Example, my towed they suggested a lube pump. However I choose an axle lock as the lube pumps can fail, the axle locks,,, Well, the technology has been around as long or longer than I have and I have yet to hear of a failure.
