Im lovin this work you guys are doing. So quickly too. It really looks like a FUN project. In a post way back you said that these are popping up more and more in your area. I think I need to start hunting in Arizona since I havent seen a one here in Texas for a long time. Its probably just that since this build has started I have wanted one of these more and more. A C20 actually would be a real investment, unlike the 26 foot Allegra motorhome that sat insured and unused for nearly 3 years in my front yard. It had F*%# 460 /C6 combo that drank a case a mile @ $4.65/gallon gas (back a few years).
I think the perfect combo for me would be what you have, with the camper that could be removed and a dump bed set-up to run around in. Work and play in the same truck! I wonder if this has been done... they say nothing is new under the sun.
Keep up the awesome work, then post picks of you and the family around a campfire with that beauty in the background. At the pace you are going it will be soon!
