Any updates on availability of dimensions and drawings?
Overall fantastic work on these campers. I'd offer some feedback that there are two things keeping this from being 'perfect' and causing me to get out my credit card, both having to do with the cabover:
1) The 48" cabover could end up being a deal breaker us for without a really good bed extension system (which looks like is pictured in the renderings). Unless there are concerns with structural stress, going to at least a 60" cabover seems like a no brainer. I can't image it would increase the weight by more than 20-30lbs, which is probably what the bed extensions most people will put in there will end up weighing anyway (and then you don't have to design around them). And if it is to preserve roof space, a very large percentage of folks are running crew cabs which have plenty of roof space for a front rack even with the additional 12" of cabover. If I could have it my way, I'd do 75" to enable a NS arrangement as opposed to EW (which would make this perfect).
2) The space between roof and cabover seems like it could be reduced a few inches. As commented, this really hurts MPG as well as looks a bit funny (if I'm honest) by lowering the cabover and keeping the ceiling height where it is, you could retain the low overall profile while bumping the cabover height by a few inches (which would help the EW arrangement work better when climbing over each other). Perhaps this will end up fitting just right for the taller cabbed trucks like the Fords, but worth consideration otherwise.
You're building a great product, so please don't take any of this as criticism, just hoping you might be willing to consider this feedback to make it perfect and see if others agree.
