"But the pure fun of beating the odds, proving yourself to be different, surviving the tuff times, and looking back on the experience"
That's the goal mate. A bus seems to be the logical progression.

We beat the pants right off the motorhomes. I had pondered gutting our steel frame gulfstream but it's gas, fairly low, and under 30 feet. With 3 kids, 3 very big dogs, 2 adults, and all of our gear we could do with more space for life and cargo. As much as I enjoy a 454, pulling a jeep through the rockies I would feel better in a diesel with an engine brake. We're pretty rough on our things and need the durability and ease of repair a custom interior can provide.
It's really just a matter of where to start and having a go i suppose. I'd like to research from now until june or so and make a purchase in the early summer and hopefully have enough time to finish the build by freeze up or finish enough to head to the beach for winter.
Thanks for the welcome. We're slightly mad to be sure.
