When we bought our 2016 37F, the first thing I noticed was the lack of manuals. The coach operators manual was there in the bag, just not much else. So, I started looking for electronic PDF copies of everything. I mean, even the tilt bed has a manual! I needed the bed manual to fix it (had to hit the reset button underneath the bed to get it to move!) and found out the bed needed to be calibrated to the full up position and the full down position to work correctly. The little things you learn! So, I have collected copies of virtually everything and placed them on my iCloud so I can access them from iPad, iPhone, and PC.
Another good thing to do is start an inventory of all your appliances, electronics, etc to include model number, serial number, date of manufacture. I keep everything on a Word document on the iCloud too. Just in case I needed to know the model and serial number of something to order a part...say the water filter for the residential fridge. Do the work now to gather this info and your life is so easy later!
