I'm totally out of the loop on newer campers and trucks.
I remember slide in campers on trucks that had sliding rear window,
with a doughnut between truck and camper and you could crawl from cab of truck into the camper.
Is this still available these days?

 

We had that when I was a kid,,,,not sure I could fit thru there anymore

 

It's not for me .

 

I have seen the style where the whole rear window is taken out and re-gasketed to the fiberglass capper, or just the inflatable "donut" that goes between the rear slider window of the truck and the slider window in the capper. I am not sure I would want too wriggle through the donut style anymore, though I had one on my '95 Dodge 2500, 20 years ago for camping with my dogs out in Colo..

I am not sure if they are still available, but try googling "truck to capper window gaskets", or the like.

 

I remember those, and the donut. My neighbor had one. I remember it constantly squeaked if the truck was moving. Oh those were the days.

 

I had one of those. The donut chafed the cab paint and we rarely used the feature. My current RAM rear window is one-piece and I like it. The Four Wheel pop up camper has the front slider, but its only used for ventilation these days.

 

Yes sir almost all TC's have the window, but my 2003 Lance did not line up perfectly with the truck window, a foam doughnut mite work better than the air up one.

we never did it but I though it mite be good for the dogs to go back and forth.
