Good to hear that your maiden voyage went well with no major screw-ups. Now that you've done a trip with your friends, do another trip to a campground or what ever you're going to use the bus for the rest of the year. Camping / traveling etc. and try to make the interior changes to suit ALL your needs.
This vehicle was designed for going to rocket launches with groups of friends. It was never intended for campground use. I don't even have a power connection right now although I will be adding one. The generator is the only source of power at the moment, but for this trip we boondocked so we didn't need an external power connection.
I have no intention of ever going to a campground although I will try to get to a rally or two.
We didn't have any heat for this trip. I had intended to install a Proheat I bought, but we may just go with electric heat to save on bay space. If the weather is cold we can just run the generator. The generator probably consumes more than the Proheat, but we rarely need heat.
