    Van floor tips, climate considerations?

    We are using Thinsulate(TM) AU4002-5 under floors. It is super easy to install. Roll it out then put your floor on it. We have used minicell foam for many years as well. Minicell is a little more supportive but Thinsulate(TM) is adequate and offers better noise reduction. We do recommend PVC...

    Savana/ Express Van Builds

    Greetings Savana/Express enthusiasts. We are now able to produce vent adapters for the Savana/Express vans. Our adapters absorb the contours of the roof and provide a flat slightly elevated platform for the RV vent. We have been making these for other vans for some time. All the best, Hein

    Insulation (thermal and sound) Suggestions?

    Thanks for the mention. (our contact info is at DIYvan.com) One issue we've seen with fiberglass is if it's not well contained then you'll be breathing it. Small fibers tend to shake loose from vibration and air currents (opening/closing doors) can blow/suck them out of the wall cavity and...

    Parts for 2017 Titans

    Do like the features of the Pro4X but didn't want the lift. The truck we got has most of the creature features. We are enjoying it and looking at having our chrome grill surround and bumper color matched either with vinyl wrap or paint. Leaning towards getting new parts to have painted and then...

    Parts for 2017 Titans

    We are also new 2017 Titan SL crew owners. Planning on getting the chrome grill and bumper wrapped or painted body color (gun metal). Then some black wheels but no lift or anything off-road planned. Got it mostly for towing the boat and highway cruising. But can't help modding stuff so who...

    Van Compass Ford Transit Build - 1 TON 4x4 conversion

    Great Transit build and cool to see what you are coming up with. The FrostKing self adhesive foam duct insulation is a good alternative to Dynamat, etc. But it's not R3. Closed cell foam is typically about R3 per inch so with a product thickness of about 3/16" your not getting a lot of thermal...

    New Sprinter 144" 4x4 owner. vapor barrier and insulation questions

    Congratulations with the new van! Most all vehicles have some design issues that leave us wondering. We used 3M Windoweld to seal the shopping cart trim clip holes from the inside. Thinsulate(TM) won't absorb moisture so water will run through and out the drains. Don't drill holes near the...

    Critique my electrical diagram please

    Credit for the inverter->inverter/charger system goes to Dave Orton. He explains it and has a diagram here: http://www.ortontransit.info/electric.php The vehicle powered inverter provides 120V power while driving. This is used to heat water and air and also charge his house batteries via the...

    Target R values for surfaces?

    Thank you for writing. The smallest roll of 3M Thinsulate(TM) we offer is 5 linear feet (@60" width) so 25 sq ft. It would be an appropriate noise and thermal insulator for the areas you mention. We stock 3 varieties: SM400L, SM600L, AU4002-5 and also have Low-E (3/16" closed cell aluminum...

    Target R values for surfaces?

    Good points and please allow me to suggest another material instead of Roxul or Fiberglass. 3M Thinsulate(TM) SM600L is specifically engineered for use in vehicles and passes FMVSS-302. It's hydrophobic so moisture does not affect it. Impressive noise reduction as well. Based on the feedback we...

    water heater

    Isotemp water heater using engine heat is very nice for our Sprinter. Water is hot after a 20 minute drive and stays hot for hours. It also has a 750 watt element. All the best, Hein DIYvan.com

    Creating a Level Surface for Roof Vent Fan Between Ribs in Van Roof

    The gap and roof curvature isn't too large that butyl tape would not work. Just use two or three layers in those areas with more gap. Looks like there is a roof coating that you might want to prep first. We can make an adapter but wouldn't have that ready for you until sometime later next week...

    Creating a Level Surface for Roof Vent Fan Between Ribs in Van Roof

    Kim mentioned that you called. We make adapters for other vans and would be happy to add the Express to our list of supported vehicles. Can you post or send a photo of where you would like to place the vent? Then we can take it from there and let you know when we have an adapter ready for you to...

    Let's discuss the on board water storage setups.

    We have 5 gallon dedicated drinking water tank built into the back of our galley. Very glad I made provisions for it. We have great tasting water out of the tap at home but mostly fill with jugs while on the road. There is some really bad tasting tap water out there, imo. We also have a 25...
