I always keep a few Pennzoil Ultra Platinum 5qt jugs on hand for the Bronco, whole house generator, and other equipment. I have been having trouble finding Ultra Platinum, but Walmart had some nearby and had 5 delivered.
I got 2 of these at Harbor Freight (on sale) for less than $2 and are super bright. Super glued the Velcro on - current glue melts in the summer heat - and slapped them on the roof. Super bright and I can add as many as I need and move them around as needed.
Nice! A long time ago I mounted the fork mounts to a 2x4 and stapled an old inner tube to the bottom to keep it from sliding. Still use it with some of my cars.
The Banks cover is an interesting design - e.g., ram air cooling, integrated o-ring, etc. I enquired about it for a Bronco and they have no plans - likely due to the ram air portion of the cover hanging lower and would be a disaster off road.
