I just followed your video link. Outstanding job! Good for you and thanks for sharing. You have done a quality job, took the time to do it right and your efforts will reward you for a long time to come. Enjoy the camper. The "skill" to do what you have done is well respected amongst those of us who know what it takes and you have it.
The rude person, let it go, ban/delete it. The lack of respect does not even justify a response. I know it feels like a face slap, had it happen to me before, but "you" know what you have and it is good. Get rid of the jerk response and go have fun camping. There is more good folks out there then the few miss aligned ones.
A retirement project is to do what you have done, just a bigger camper. OK, where did you get the paneling? Elkhart area surplus?
Thanks
John
