Thanks for watching, and I’m glad you found this helpful!

Copy away! We love paying it forward! We didn't add foam to the trim ring for two reasons: 1) didn't want to add any extra "bulk" to the ring when adding USB ports and fitting between the wall panel and flare, and 2) it has such a nice smooth surface it really didn't need it. When we finally install our bed system, the mattress will be custom cut to sit in the flare, so the bottom of the trim ring will be covered (thus why we have the seam line on the bottom of the ring). We did line the flare with a thicker 1/4 inch landau foam to add some "insulation", but the rest of the van in 1/8 inch foam on all ceiling and wall panels. We also added 1/8 inch foam around the top of the sliding door and C pillar and around the back door pillars to also give it a smooth finish before wrapping with fabric. The only place I didn't add foam was on the foam trim rings for the windows (came with AVC Rig Kit), and the pillars behind the front and passenger seats (I believe these are the B pillars). For these, I just glued the fabric directly to the metal.

Ahh, that makes sense. Thx for the response! I'm looking forward to seeing your bed and cabinet videos. @@blazingwanderers
