HAHAHA 150 mile social distancing. That's great! No I haven't measured the overall height. I know Grand Design Specs say 12'3" but I have a 2nd air conditioner and when hooked up, those numbers change a lot. Getting from the dealer to my home, it's all interstate and roads without bridges to go under so I'll be fine regardless of the height getting back but measuring the exact height is on my "to do" list. They had to order a new wedge part for the pin box (the one that comes with the Sidewinder doesn't fit right in my B&W hitch) so I had to leave the dealer without the trailer. I'm a little bummed out but better to be safe and have it right than to risk things.
