Adding a sliding window to a van conversion

I’ve wanted to add a driver’s side window to my Promaster 2500 van for a few years now. Thanks to a forced rebuild due to a collision — that’s a whole other story — I had stripped out my van’s build to bare walls, so that the bodywork specialists could repair the damage.

If I was ever going to add a window, this was the time.

Finding the right window vendor

First, I had to decide on what window to go with. I knew I wanted a sliding panel and a screen to add airflow and keep bugs out. The tricky part was deciding on which model to order..

Van Tek Glass, Campervan HQ, and a few other vendors online had windows in the price range I was looking at. The windows ranged from $350-$850, depending on the size. The cost of shipping was a substantial add-on cost, which made the estimates vary wildly.

After scouring the options online, I discovered Motion Windows. Once I realized they were based locally in Vancouver, Washington, I knew I had found an ideal supplier. Not only could I support a local business, but the windows are made to order. It also meant there was no shipping cost, which was a big deterrent from the Van Tek models; though they had the lowest pricing, the shipping cost almost doubled the final cost.

Motion listed the window at $467, with a discounted price of $373. Sales tax added about $50, but it was still a fraction of the shipping cost from other vendors.

The product I decided on was the 159″ Wheel Base Ram Promaster Side Panel T-Slider window. It had Interior Frame-Fit Dimensions of (W x H): 43-3/4″ x 19-3/4″).

Walls, bed platform, and sink reinstalled. As part of our van redesign, we also planned on having a bench seat installed for a future child seat.

Installation

Although the installation looked within my ability with the assistance of an experienced friend, I decided to have Pro Motion do the installation. The total with a $200 installation fee and sales tax came to $634.37. Even with the installation charge, it came in close to what I had budgeted, and it cost me less than other options, saving me at least a day of effort on the overall van project. Though my friend Jason had the tools and experience of installing windows, the immediate gratification felt worth the fee. I also had to reassemble the van and build a window frame, as well as perform other tasks to get the van back to trip-ready.

The ordering and installation process was easy. I ordered the window, then followed up with setting up the installation appointment. On the day of the install, we drove over and dropped off the van. It’s located a few blocks from a local Walmart and a Starbucks, so we walked over and enjoyed a coffee until they contacted us to let us know it was ready.

Bench seat installed! Now to starting the framing.

The window is spot-on what I was looking for, and with the installation done, my next task was to start working on framing it out so I could put the wall panels back on.
