One more advantage of extended cabover on a regular cab PU

I liked the shade it provided when driving.

specta - I appear to do ever thing bass ackwards. I have a Ford Fordor 350 with a vintage Bigfoot east west bed. Most of my front doors stick out ahead of the camper overhead.

so my front winda will get frosty

BUT

annoying cross wind side wind angle wind messing with the cab aero's so the top of the doors have wind whistle air leaks racket?

Nope. Quiet.

Is yours quiet way back like that?

Main purpose of owning RV for me is avoiding places where I can have frosty windshield.
On other hand, my truck had Super Cab, so the cabover was sticking up front quite a bit.
It hit me one time, when I drove the truck empty that dashboard was getting hot, regardless AC working very well.
It is one of those feeling that something is not right, or not as it used to be and took me a while to realize that without cabover the sun is warming up the dashboard way out of proportion to what I used to have.
Super Cab sits 6 comfortably, although I never had passenger heavier than 200 lb.

Funny. You give up a lot of space to keep the windshield clear. :D Fwiw, I had 6 people in my crewcab on a trip this year. You can’t really do that with a regular cab. ;)

The winshield on my class C has never iced over.
