I like Petro's. Their one of the only truck stops left that still cater to drivers. Pilots and loves are glorified gas stations. Flying J's are places to live in your car, sell drugs and give your kids back to their moms on your visitation weekends. I'm still trying to figure out what TA's are...
All those specs and math are interesting and useful but to me what's even more important is that the generac doesn't have (not yet anyways) the reputation for reliability that Honda has. Warranties are important of course, but when there's an issue out here it's a huge inconvenience for us...
It's probably not as dangerous as you think. By the time the information gets to your phone I'm sure it's in a different location. Its traveling a few hundred mph. Besides, I've always been able to look up and see where a few of them are.
I don't think most setups are heavy enough to effect any of that to much, but I can't get it through my head that's it's ok to block any air from getting to the front of the truck. I figure all the vents up front are there for a reason.
