I just wanted to share this info as it may be very useful to those of you who want to do their own maintenance or customizations to their Sprinter-based motor homes.
There is a forum of Mercedes Benz Sprinter owners, mechanics, outfitters, etc. called "The Sprinter Forum." It is free to join and use. It is full of all kinds of information, questions, answers and useful stuff on Sprinters. I have found tons of helpful things on here.
Here is the link: Sprinter-Source.com (https://sprinter-source.com/forums/index.php)
You have to register to get full access to the site, but that is free and easy.
I hope you find it useful!
I agree the Sprinter forum (Sprinter-Source.com (https://sprinter-source.com/forums/index.php)) is a valuable source of owner info. Besides general Sprinter info, it even has a well supported section dedicated to LTV Unity specific issues. These guys really know their stuff.
As a cautionary note, stay off the "Off topic" sub-forums that are totally unmoderated and full of political arguments and incendiary rhetoric. (unless that is your thing)
