Safety Mod Pass Through to Truck Window

I bought a boot to go between the camper and truck window direct from Northstar when I bought my camper. I think they sell to the aftermarket. Only takes a phone call/email to find out. www.northstarcampers.com/contact-us It's a nice Naugahyde(?) covered foam cut to a slight wedge shape so it fits snugly top to bottom. The foam is soft enough that vibration isn't transferred through from truck to camper so I've seen absolutely no where on the paint. I primarily use it to pre-heat/cool the camper while on the road. Open the rear vent, set the truck climate control to pull outside air (not recirculate) and the camper is very near the cab temperature when I pull over. It's also handy to get to items on the back seat from inside the camper. One of these days I really need to take some pics of it as frequent as this question comes up...

The simplest one I've ever heard of is using a bicycle inner tube. You position it, then blow it up in place. No personal experience, but I always wondered if it might squeak if there was too much movement. Silicone spray might fix that though.

I think those talking about trying to fit through the opening are missing the point. One of our points was letting the cats go back and forth. We had platforms so they could travel looking out the crew cab windows, but they also needed to go to the back to use the cat pan. Another essential reason is heat and A/C. With those passageway open the truck will heat or cool the camper while traveling. If you open a vent that will help the air flow. Usually we did not find that necessary.

You will need a "donut" or boot to form a good seal between the truck and camper. We have a specially made vinyl covered foam filled boot. We got it from our dealer who I believe got it from Northstar. I saw it listed on the Northstar webpages.

Lance Camper dealers sell a foam rubber boot to go between the camper and truck; I had one on my old setup. I think it’s overpriced but if you do a web search and see a photo of it I think you could make one much cheaper.

Google camper boot- there are a bunch, like these.

You would have to very slim and limber in order to fit. Also the window in the TC looks to be off center and would not line up with the truck slider opening, unless you have a Tundra or a Tian.

Here is an example of what you would need to do:

Unless you are absolutely tiny, you will have to modify both the rear window of the truck and the front window of the camper heavily to achieve this. The stock openings are much too small for anything bigger than a small child to crawl through.

Generally speaking what you are trying to accomplish is not practical, even for emergency use. It will be a custom one-off solution for your particular combination of vehicle. You would need to find a local customizer to do the job unless you feel capable of doing the work yourself.

On the camper side it would require complete removal of that front window and enlargement of that hole, if there is even open wall space there to do that. It would also require removal and modification of the back glass of the truck to provide a bigger hole.

I do know that years ago you could get an inflatable "donut" that sealed that area between the camper and the truck. I think it was in the JC Whitney catalog. Haven't seen one for sale in many years.

Honestly, if you are THAT paranoid about being "attacked" in the night and having to make a quick escape by diving through the pass-through into the cab of the truck, you're in the wrong business, camp in the wrong places, or should re-think camping altogether.

could be as simple as This

But I can see this would wear the paint on at least the truck. so you need do weigh the reasons. I know I personally would not fit through the window on my Arctic fox even if my truck DID have a opening rear window.

Unless you are small people this doesn't seem pactical. I would talk to Cirrus for the TC side assuming you can also get through the truck window.
