Thank you all so much for all the wonderful comments. You guys are great and I am glad I decided to share it with all of you.
The ceiling height is 6'2" and that is how tall I am, so if I stand up straight my feet are on the floor and my head is on the ceiling. Just enough room for me.
The conversion process was amazing. My son and I really worked well together. You wouldn't believe how much he was able to do. He tinted all the windows except 3 which I did to show him how, cut all the wall studs for me, cut a lot of the paneling, measured, cut, painted and installed all the trim. I also taught him how to weld when doing the tanks. There is so much more that he helped with I could go on and on.
I am very fortunate to have such a great son. However, I also have three daughters that are great as well. They all helped out here and there but this project just wasn't up their alley. We all are enjoying the work we put into it and are having a great time on this trip and none of us want it to end.
