We have a 2013 30RE. It did come with the remote but I don't use it ....... the battery in it died and they cost $12 each. I believe they stopped providing the remote in 2014 because of possible problems with slide or stabilizers operating while driving down the road.
As far as things to check; awning operation/lights, smooth slide operation, stabilizer motors, and possible signs of water entry.
