I had to reroute the plumbing on the fresh water tank on my AF865. The intake to the freshwater pump is at the top front of the tank. If you are parked nose high you "run out of water" rather quickly because it is such a long tank.
My 865 is a 2013. They may have changed the plumbing in newer models to fix that problem.
That and the rat's nest wiring under the step up to the bed are my only real complaints. It's been a great unit otherwise.
I second the thought about hauling it on a dually. We sold our SRW in favor of a Dually and the difference is night and day.
