First, welcome to the forum. If you can't find an owner's manual in the Sprinter, go to Keystone's website, (
www.keystonerv.com), click on "Customer Service" and follow the Owner's Manual link. It can be downloaded from there.
Be aware that Keystone does not create specific Manuals for each model. Instead, the manuals are all generic - one size fits all. There are some sections of the manual that are useful but you may be disappointed if you are looking for something specific like wiring or plumbing schematics.
