I recently purchased the above mentioned travel trailer and wanted to know where I would get access from the inside to the water heater and water pump? I have one more trip this weekend and then it is time to winterize.
BTW, I love the trailer! It's a great fit for my wife and I, the quality is good and the layout is perfect.
I'm not familiar with your Aspen Trails but on a majority of the campers out there, you will find either an access panel that is screw down or it is under your couch/dinette. So depending upon where your exterior access is for your water heater, look inside the trailer at that location for your bypass connections.
I have owned two different TT's; one TT (a Layton-310) had the water heater under the couch and my current Kodiak has the water heater behind a panel in the rear bedroom which is access by removing 4 screws.
