2nd update after a year of ownership.
Quite a few more problems, I'm still happy with my purchase nonetheless.
-all the caulking everywhere cracked and pulled apart over the winter - not pleased, I had to redo it all
-AC unit cycles incorrectly, kicks off and back on immediately constantly in warm weather... If I put the thermostat to maximum it stays on but gets too cold.. indicating this to be a thermostat issue. I called Dometic, they wanted to send me to a place 2 hours drive away to have the unit serviced..... rather than the place i purchased it from new 15 mins down the road. I tried remounting the thermostat further away from the wall, and sealing the 1 inch hold they drilled for small wire (assuming some warm air might be coming out of that hole from the wall... it seems to have helped.. but havn't used it enough to tell for sure.
-numerous plumbing leaks due to not tightening fittings properly
-got the recall noticed, called my dealer... took them 2 months to get the part in from Heartland.. now the part is in, but still haven't scheduled me in to swap the gas line.
I'll mention Again - I did lots of reading before purchasing this Pioneer trailer, and almost every brand in this price point has nothing but horror stories on all these little things, so I was expecting this. I am still happy, but we'll see how it goes from here.
The good: for the most part I absolutely love this trailer.. it's perfect for what we need, it allowed us to take a 3 week road trip with our little toddler last August, and we have a 2000 mile trip planned in May!
