Hello. I have recently purchased a (new to me) lightly used 2015 XLR 29HFS. I am new to the forum and this is my first camper. I have, in the past, used a travel trailer on occasion that was not my own so I am fairly comfortable with the towing / set up aspect. I have a 3/4 ton tow vehicle with a WD system. Towing home went very well. The dealer went over all of the features with me but I have a few questions remaining and the owners manual seems to be a little lacking in specifics. There are two switches on the outside water hook up panel. One is labeled light and one is labeled pump switch. Neither seem to do anything. The city water connection as well as the transfer switch to fill the tank seems to be self explanatory. Everything else seems to work as it should other than a few outside lights the dealer is sending me for replacement. Also, are there any tricks / advice anyone can offer me for this model to keep me out of trouble in the future? I am excited to be part of the forum! Any help would be greatly appreciated!
