My beef with Coachmen (which is a Forest River company) is that as designed the 30 gal fresh water tank on my Freedom Express was inadequately supported so after the first fill it sagged noticeably, as shown in this pic.:M

I saw this as a matter of time before the tank would literally fall off the trailer but also because the pump intake hose was connected to a fitting on the tank
sidewall there's no way the pump could fully empty the tank. I immediately had my dealer support the tank with metal braces, moved the pump intake hose down to the drain port, and later added my own 4' x 2' piece of wood as further support. Now I can travel with a full tank if necessary and the pump can empty the tank completely.

My 2014 model has an open underbelly so this was easy to spot but I pity those who have purchased a more recent model Freedom Express 192RBS which now has an enclosed underbelly as my understanding is Coachmen has done
nothing to better support the fresh water tank. :(
