Thanks Gizmo, I'm definitely doing some rethinking, your idea is very good. I have always used 4 straps but this time I used two in the front and a bubbie wrap on the back wheel to hold it to the carrier. I'm going back to four straps. I have in the past attached the inside straps to the truck chain connecting points and when I tightened it would stop the rocking horse effect of the bike rail.
