Wow, what a horrible experience. I'm glad they were able to give you your old pop-up back. We bought a 147x in July of last year and it had a few issues too. When we were doing our walk through, they were showing us something and there was water on the floor. They checked the water pump and the cap or something (it was round and clear) was never installed properly and looked to be warped. Thankfully they fixed it right away and cleaned up the water. There were a few other superficial issues that could wait until the season was over, but mostly it was fine. The other issues that happened while we were camping was one of the window valances fell off (the screw stripped out), one of the burners on the stove broke, the railing for the detachable outdoor grill began pulling away from the wall of the camper, water leak through the rooftop AC unit, and the worst was our power converter box went bad. Thankfully these didn't all happen at the same time, but made our last couple of camping trips a bit more interesting. Once the season was over, we took it back to the dealer and everything got fixed. Took awhile, about a month, but it got fixed. I hope your next camper purchase goes better and that you find a reputable dealer.
