Great underbelly enclosure videos

For folks who (like me) are thinking about tackling this big modification project, I'd recommend these two videos:

Part I

Part II

The videos are kind of long, but I think that most of the length is necessary -- he explains what he is doing and why, and there are some very useful tips along the way. For example, he recommends removing the stabilizer jacks before installing the insulation and the coroplast, and then re-installing the jacks, thus providing a much better seal for the underbelly covering.

He also recommends undoing the propane lines as needed, so that they can pass through the insulation and the foam. That's a little worrisome -- I hate to disturb a non-leaking propane connection -- but I think his idea is worth considering, and I may imitate his method.

Watching the video carefully, I don't think he drilled pilot holes for his self-drilling screws. That method seemed to work well, so I need to re-think my plan to pre-drill everything.
  • Well, I posted a comment on his video, and he just wrote me back saying that he did not drill pilot holes. I will try this on some thick scrap steel to see if I can do the same. I would have thought that it was not possible.

    He must have used super-screws if he drove them into the structural frame members. I suspect he just did not show the hole drilling.
