we'll see, it's already installed i tried pulling the rakes out, it takes some effort, the springs are real strong. I did mount the track on the forward rib so i can if necessary mount those velco strap mounts on the back rib of the roof stringer, meanwhile i think the velcro strap mounts will come in handy in mounting the tile spinner to the roof. I ordered the
hydramaster wand mount system, my thought is to use 1 of them to hold the spinner end of the sx15 and 2 of the velcro straps for the handles so thank you for the idea ill post pictures when i get it up there, also i intend to mount a gekko tile handle and a scrub wand somewhere in the van ill post the results thanks for the input and advice
