Wow - I was doing a web search and accidentally came across my own post from five years ago. It's now 2022 and I've put thousands of miles on my rig. I don't think there's a single system that I haven't done something to at this point and feel like a real expert! I've replaced all the cushions, seats, WALLs and door coverings. I've remounted the water tank, replaced tubing, you name it. I've even replaced the isolator and internal power supply. It's running great!
Recently the little right-angle intake tube inside of the water heater popped off, but I've ignored it. I may someday replace that heater, but it seems to be fine at the moment.
I'm still very much impressed with the build quality. I wasn't at first - but then I started looking at newer models and realized those Canadians knew what they were doing!
