I use the Reese sliding hitch and have used this hitch since Sept 07. The hitch has been in two different trucks with both trucks using the BED Rail System. I just pull four pins and lift the hitch out of the truck when needed. There are all types and makes of hitches, so if the price is right than I would purchase the hitch.
When we purchased our first 5er the hitch installation was provided for free if I purchased the hitch from the dealer who sold us the 5er. So I agreed with the dealer and purchased both the hitch and 5er from them.
