First question how tall is the grap pole from the ground, I mean will it clear in a 7 tall garage door? Second question what are the opening size on the 2 boxes on each side of the net box. I have some large storage boxes that I keep first aid kit and other items, just curious if they will work when my P4 show up in the coming weeks.
You should be fine as far as the boxes they are about 10 in. x 20 in. that should be plenty if not the center box will hold those few things with ease. The grab pole Im not sure about though. My boat doesnt have one as mine is an 06.
The Grab Post is designed to go in a 6 8″ garage header. We would have to measure that to be exact. You can also roll it in with the tongue jack lowered if you need to.
