I have confidence in ESOF now, I also have a '70 Bronco Sport. I too think that it has been out long enough for it to have few problems. Plus, I know a guy the has and F250 and a brand-new F150, both with ESOF and we go camping. He's never had a problem. Especially when the guys drive thier sandrails off the cliff and the guy with the F250 had to pull them out.
