Fat Framer

Anyone here have the Pullrite superglide and also have the pullrite gooseneck adaptor that fits the super rails. I use the 5th wheel for my RV trailer and I want to get a new enclosed work trailer w/ gooseneck to fit the super rails. I dont want to use the 5th wheel for work because it is to heavy to remove when I disconnect and have to leave the job for material. The gooseneck should weigh alot less and store easier. Just looking for feedback on pullrite's adaptor.
And yes, I do have a slider hitch on 2 full sized beds. It gives me more room in front of the trailer and the hitch came with the trailer.
