here's my setup:
-bbq rack w/ pelican 1520 bolted through. pelican is mounted rearwards 1" from the from of the rack's front edge, so i can loop the 2 center straps on the coyote around the front edge of the rack.
-giantloop coyote bag. sits on the rear part of the seat. straped to the front edge of the rear rack (w/ 2 center straps) and the passenger pegs. fender strap not used. holds rock solid. sometimes i strap something else (a round top-loader dry bag) on top w/ rox straps. it sits in area between the pelican and the top of the coyote. don't want to put too much weight onto the pelican/ebay bbq rack mounts.
-i'll use one of those helmet/bungy style nets w/ multi hooks over top the pelican top surface to quickly stash a linner or towel to dry or something light like that.
