Happy with our pass through
Hello Butch:
Congratulations on your truck. We've had an EarthCruiser for nearly two years and we're very happy with the Fuso FG platform and (dare I admit it here?) the 6 speed Duonic transmission as well as our pass through. For us the main advantage of the pass through is the cab of the truck becomes part of the living space / house. The passenger seat has the best views & is one of the most comfortable interior places to enjoy a cup of coffee while watching the sunrise, etc. When one of us is there and the other is in the house it's easy to carry on a conversation, pass that cup back for a refill, etc. I have crawled from the cab to the house or from the house to the cab, but that isn't a major benefit for us. Basically it's the 25% increase in our living space that we can't imagine giving up.
We do travel with a dog and he spends 95% of his travelling time in the pass through where he enjoys the views through the windshield and riding in close proximity to the rest of his "pack."
Others here are much more knowledgeable than I am about the pitfalls of constructing your own pass through - personally I wasn't interested in doing that so I was happy the EC folks had already done it for me. Ours doesn't leak, we don't notice the extra noise if there is any, and we don't feel extra heat from the engine via the pass through. If your interested in a pass through I wouldn't be discouraged - for us it has been extremely beneficial. However, I would seek a professional installation from someone who had worked out the bugs, etc.
We're south of you in New Mexico. Hopefully our wandering paths will cross - maybe we should get together for a west-east run of Medano Pass? We did that last year and enjoyed it a lot.
