Hello all, I have just bought a new TRX. It was delivered to me, so no walk through. First question, I have bought one sewer hose, that because of fittings on each end, will not fit in holder. It is about 3 and a half inches in diameter. Can any of you recommend a brand that will fit. Nothing in manuals to help me. Second question, the gauges on wall, what does the esc reading mean. It is blinking red w/different numbers. Again, nothing in manuals. Also, water has leaked, maybe from window, and is under sofa on floor. For those of you with experience, do I just need to caulk window? Thanks in advance for all your help. I feel stupid asking these questions because I have owned several motor homes, but Philly is not calling me back!
