I’m trying to plan an epic Father’s Day gift for my husband. He has this beautifully restored FJ40 in the garage and it doesn’t get much use. I thought it would be fun to get him an awning for it and create a summer bucket list for our family with links to off-road locations we can visit. I’m trying to figure out how this awning thing works. Can it be mounted without a roof rack? What would I need to invest in to accomplish this goal? I’m assuming he’ll have to put it on himself which he can do as he is pretty handy, but I just need some direction. Thanks!
