Thanks for the info , I leaning on building a couple custom two piece spacer that will be easier to load and unload . Also the build will incorporate a centering rail that should help center the camper when loading .
My f450 has cab lights so I have to be careful to be sure I have plenty of room to move .
I'd like to trade it in on a newer one but I just can't justify the added cost for the amount of use. With any luck in a few years I'll hit the road of retirement then it'll get used a lot . JW
