Hi JJAM,
The Heartland trailer manuals are pretty generic and are updated infrequently. They don't get into the details of each model/floorplan.
If you don't hear from another 2017 Edge 351 owner, you can call Heartland Customer Service at 877-262-8032 / 574-262-8030. Have your VIN # ready. They can tell you what's what.
As for manufacturer manuals for appliances and subsystem devices, we have a large collection of manuals on the forum. Click on the TOOLS tab near top of page and select
HOM - Heartland Owners Manuals. There's a pretty good chance we have anything that didn't come with your Edge. If not, most manufacturers have appliance manuals available for download. If you find one we don't already have, please forward it to
manuals@heartlandowners.org so we can get it posted.
