Rick Stewart said:I too looked into a fiver to GN conversion and rejected it for these same reasons. Some manufacturers do caution about pin box issues and require minimum pin box construction criteria before allowing use. Still not enough for me though.
On a related subject, has anyone used the PopUp extended GN coupler (SB1)? Looks like a good solution to short box towing for a GN.
Any comments on safety or stress issues as with the GN adapter?
