Our 2014 2500TS came with generic manual, not specific to model, best I can find out that is all there is. For someone who is new to RV, that makes it tough. For as much as we pay they really should have a model specific manual, plus our sales person knew little about our 2500TS, so our walk around was not much help. Service techs gave me wrong info on several things too. Every time I use it I learn something new.
We did get a specific manual for air bags, values to add air are in lower, rear storage areas. I put 60 lbs in mine and that seems to work well so far. If you can not find the manual, let me know and I will let you know what web site to check to see if they have manuals on line.
We just got back from camping 7 hot days, our AC did cycle on and off some but not a lot. About two or three times a day it would turn off, then back on in a few seconds then off again. I assumed it was the fan only and not the compressor but not sure of that.
Our walk around did not include the low point drain either, so I will have to find mine too.
Good luck.. Emory in MD
