Check this out. This may help out some folks who are wanting to haul 5th wheel. I am in the process of figuring out how to pull a 26 foot 5th wheel RV. The problem I have to over come is that I have a crewcab witch makes my truck bed one foot shorter then those on the board towing 5th wheel whit kC.
Below is a link to an extender for 5th wheel that I will check out to see if it will solve my problem. Its model RV5.
