His opinion is only worth as much as you paid for it. You built what you wanted. If he wants something else, let him do it. Just took a look at your video and FWIW - no charge for this opinion - I like it! Of course, you'll probably miss the opportunity to tighten a dozen or so screws missed at the mfg or tweak other things, but that's the breaks. Nice job, excellent price, pride of doing a good job, lots of great camping trips coming up. I wouldn't invite this person to join in the fun....he needs to be busy building his own camper.
