I've heard the same about versatube instructions. I know Handeeman on YouTube built a huge versatube shop and he ran into issues after he started putting it together and had to redo a lot to make sure it was all correct. And yeah permits suck but you gotta pay that county/city bribe to let them do what you want to do on your property. I luckily didn't have any issues with permits on my shop in Phoenix besides them making me get another permit for a concrete driveway through the gate that was already there since the home was built 10+ yrs before. I also ONLY permitted the structure, Not the electrical, bathroom, plumbing etc that I added after the building was done. Then when I sold the home I just had to put on my disclosure that those items were not permitted, but that didn't effect appraisal and most likely only increased the ease of sale with those amenities in the shop.
So almost back on the Baja350. You'll get back on your before I'll get back onto my truck, I'm jealous. lol
