Well, here's an update. We have a younger couple living in our bus and they love it! The rental's here are sparse and mucho expensive, as we are a ski town. I have three heaters in the bus and with them on low to med it's as warm in there as my house. I just hooked up the waste system. I opted for no tank as it seemed a huge hassle and the bus isn't going anywhere soon. so it is the sink and shower (1.5" and 2") tee'd into the 3' toilet waste, then run into my sewer connection. Works great! Thank goodness. However while pressuring it up I discovered my faucet was leaking severely so had to put another one in, which in turn caused one of the pex conections to fail as to much flex was put on the joint. Good times. But, the electronic iginition 6 gal atwood hot water tank is super rad. I've never been able to fire it up before and it is so nice. Just flick a switch and 10 minutes later steaming hot water! No pilot lights, shivering in the snow and cold. Highly recomended. So now they have a shower, toilet, sink, hot warm bus, with a fridge, stove and a microwave. I just told them they had to stay for 3 weeks so I can pay for the trips to the hardware store
Who knows, mabye this will turn into a regular thing. People in the bus during ski season that is, not freezing my but off for 2 days trying to fix stuff.
