New guy posting here. I have a 2015 extended rear, hi roof diesel in construction for a mobile office on front and mountain bikes and work/hiking/biking/camping field gear in rear as needed. I love the rig and don't regret my purchase despite having Diesel Exhaust Fluid issues twice now. My Transit is sitting in my shop stuck in limp mode but local dealer is towing it tomorrow. Maybe we can solve the issue the second time around with 14,000 miles between the same issue over about a year. I'm hopeful.
I'm new to posting (picture issues on my end) but have been fortunate to private message Orton & Hein and I have benefited greatly on my build due to those two guys. Thank you to both of them for pointing me in worthwhile directions and also to Hein for producing custom roof rack mounts second to none for my roof rack. I will post up some input on my Front Runner roof rack setup in a different post since it solves many Transit issues for solar panels and field/camping accessories like fuel, water, and gear storage. Back to the Lizard Skin.
I made a choice about 8 months ago to spray Lizard Skin into and onto every cavity, panel and nook from the roof down to the floor. I went with Eastwood Heat & Sound stick-on material (Dynamat copy) inside the front doors & slider to avoid mucking up window and door lock/latch mechanisms. I live and work as a construction project manager in SoCal so fighting heat is my issue here. Since we can't hang rigid insulation on the outside and spraying Lizard Skin on the outside is lame, I went all in to spray the interior with Lizard Skin to knock down the heat gain and I'm pleased as I can be. My #1
goal is to keep heat out and move heat out when it gets inside. I believe the Lizard Skin is holding back 80% of the heat gain from getting inside the vehicle. I installed two (2) Maxxfans with one pushing air out and the other pulling air in. In addition, Orton coached me to install floor vents to draw cool air from below, so I installed two vents, one in front and one in back, due to the future partition which will separate the front & rear sections of my interior (framework welded into position currently). I have great air movement and I use it daily. I use my van outside during the week and then on weekends for biking & hiking so I needed to focus on heat gain & air movement first, then conditioning the remaining air at a later date. Cool air conditioning is a tough equation with how to power a proper system but I'm not interested in loading up on a huge battery bank. I did install two (2) 6 volt aux batteries (solar powered), and that is my daily office power for daily use. Works great thus far with a 300 watt LG panel.
My finished interior will utilize 3M Thinsulate purchased from Hein (yes, in addition to the Lizard Skin), coupled with newly delivered plastic side panels out of Canada (a few guys on this site have purchased the same ones as well) which are going to be custom upholstered with a nice gray tweed cloth before going inside permanently. Ultimately the mobile office desk and the rear bike/work gear area will be decked out in full 80/20 fixtures, but the walls and ceiling need to go in first.
I'm open to answer questions about Lizard Skin since I seem to be the only guy who sprayed the entire interior and many seem to be searching for real solutions to heat and sound issues. I'm here to say it works very well in a warm climate and it has been the #1
modification I feel is making my build as thermally good as it can be. I can't speak to cold climates and any moisture drive issues so I won't comment on that topic. Cold climates are a different animal and I have no idea about temps below 40 degrees. Any excuse to wear a jacket is fine by me but that is a rare event here in SoCal the last 5 years.
I look forward to sharing some build experience and talking with many of you about Transits. I drive and work in my almost daily.
