Well, it's almost here. We pick up our new fifth wheel this Saturday. I've never towed one before but I'm sure I'll pick it up. I've towed regular trailers for a long time. Think my only issue will be...
As already stated, a fiver cuts inside the truck rear tires more than a TT, so you need to wait as long as possible to start the turn, then turn as sharp as possible. Otherwise you will put the trailer tires into a curb or ditch or worse.
When backing into a spot, you will need to pull much further forward than you are used to as the king pin location means the fiver will require more distance to begin reacting.
