Sorry for the long post, but since we get sparse posts for this model, I'm making up for lost time!
The maiden voyage went very well and the hitch performed flawlessly. The trailer was very tame during the drive to the campsite (no winds, mild traffic conditions). Our camp site was nearly perfectly level and made setup a breeze. The electric stabilizers did a very good job of keep the trailer stable, but I did use x-chocks as well, so hard to tell if they contributed or not. An experiment for another trip, I guess.
The challenges were in figuring out how to get the water heater to work. I received the trailer already winterized, and I had to flush the system, but I wasn't aware of the valves that direct flow to isolate the water heater. I had to find the access (under the bottom bunk, you can lift up a plywood support) and open top and bottom valves, keeping the middle valve closed. After about 10 minutes, I had nice, hot water flowing from the 6 Gal DSI water heater. I was on shore power, so we did electric only. I probably should have tested the gas portion, but yet another experiment for another trip!
Fridge, A/C, microwave, stove, oven, worked flawlessly, but the furnace vent in the master bedroom is weak and very little heat comes out. There is flow, but it is weak. Don't know why the heat dissipates before getting to this vent. I think I need to have it looked at. The furnace does a superb job of heating the rest of the trailer/bathroom though. The "fireplace" is ideal when hooked up to shore power, and I worked out a system to have the fireplace space heater function during the evening until about 5 AM (you can set the heater to operate automatically via thermostat and set it for x number of hours up to 8 hours). I set the temp on the thermostat to higher than the one on the furnace, so the furnace never came on while the fireplace heater was working. When the fireplace heater timed out at 5AM, the furnace would take over, heating the coach and warming the bathroom up nicely for the early morning risers. Worked so well, I want to make it my routine. Saves a lot on propane too, since most of the heating is done by the electric space heater in the fireplace.
As we emptied the tanks, I discovered the black tank vacuum breaker valve issue. It remained closed and still remains so. I hooked up the hose to the flush port, but as the hose pressurized, there was no flow into the tank whatsoever. Coachmen gives easy access to the valve via the bottom bunk with a panel on the wall that is closed with a couple of philips screws. I had to order a replacement vacuum breaker valve, and based on recommendations, went with the brass fitting for durability and to prevent valve failure. I'll report back on the fix when it is done.
TV is permanently mounted to the bracket, making it difficult to add any peripherals such as a game machine, or wifi video (Apple TV, Chromecast, Fire TV, Roku...) unless you remove the rear panel using square torx bits.
I plan on replacing this with a swing mount so the TV can be moved and swiveled if needed.
Return trip was a bit hairy, as Santa Ana Winds kicked up to about 15 mph with 45-50 mph gusts. The pro pride hitch worked well to prevent sway, but it's impossible to have a white knuckle moment when you get a 40 mph side gust that just moves you AND the trailer simultaneously. Overall, the Yukon XL handled the load well, and stayed pretty stable, all things considered.
We've generated a great list of things to do to the trailer and items to acquire. We're excited to hear any tips or tricks you have.
