As the title states, I'm on my way to pick up an 8' slide in for my 1995 F250. I don't like the hitch or frame mount tie downs since they lengthen my truck (for being long already) and lower the ground clearance (the Happijac I was looking at). Then I run across the Brophy pocket hole tie down which I really like the idea. I know they run this a lot in old times but I want to make sure these tie down will handle some off-road driving. The camper is the Spacekap which is about 800lb from their spec sheet. But I may add more lbs to it as the building going. Thanks in advance for any inputs!
