Send me an e-mail if you could with camper model, serial number, or original owners name.

I'm buried right now and falling a bit behind.     :(

 

But I will see if I can find measurements for you when time allows.

 

If anyone can find them, it might be me.

 

:)

 

Stan

 

Thank you, Stan - I really appreciate it. Information is on its way!

I would really like to thank Stan.

 

Not only was he able to find the build information, but he already e-mailed the expected wire location to me.

 

Kudos for some great customer service from him.

So, you're not going to share the information you received?

Add to the communal WTW knowledge base?

That's a rather odd presumption to make, and not in a very collegial manner, but so be it.

 

For this camper, the documented location is just aft of the front vent cover, and just outboard of the cover towards the drivers side. Note that this is for an early 2006 build, a Grandby model, and non-extended cabover. The location is clearly different than on the newer models, as referenced above where there would be access from under the front push panel.

 

Stan also indicated that 4WC uses a several inch rectangular aluminum plate that is welded to one of the fore/aft roof support members as a wire feed and connector support. This plate has a small diameter hole drilled through it for wire routing and for the connector. Nominally, if one presses on the roof at the expected feed/plate location, one may be able to feel additional support underneath the roof sheathing where the plate is located. It seems like this is the case here, but I'll definitely be drilling a small pilot hole and have some sealant on hand.

achiral,

 

Those instructions and the location are very similar to what FWC told me when I decided to add solar to our 2007 Keystone.

 

By pressing down with my fingers I was able to feel the coil of wires under the roof skin.

 

I removed the horizontal lift board mounted to the inside ceiling of the camper and I was able to locate the aluminum plate with the hole in it.

Here is a write up on my efforts:

I hope this is helpful.

Craig,

 

Thank you for the link - I don't recall finding that thread before. I have not yet had the opportunity to work on this project, so the install pictures are very helpful.

 

I also had not decided what type of bulkhead to use for wiring (I was considering just a basic SAE surface mount), but I see some real advantages to your bulkhead passthrough. I need to think this through a bit more since the install will be hard to reverse.

I finally was able to install solar in July, so I'm putting up a couple of pictures of the roof feedthrough. The original stated location was 54 3/4" from the front of the camper and 23" from the driver's side for the hole in a metal plate. Stan wasn't 100% certain whether the numbers were from the frame or the finished dimensions, but the metal plate could clearly be felt in that region.

 

I drilled several pilot holes to ensure I was roughly correct, then used a 3/4" bit to drill through the full aluminum sheet. As can be seen by the first picture, it appears that those dimensions are likely from the frame itself, as the hole was off 1/4" fore/aft from the hole in the mounting plate. There was almost a foot of stranded 10/12 gauge wire taped to the mounting plate to work with.

 

After a bit of time with a half-round file and some adhesive heat-shrink butt connectors, I had an SAE connector ready to install with some #10 x 3/4" self-tapping stainless screws.
