Hello!
Yes, we've been very happy with our 5'er. Our longest trip was from Bristol, Vermont to Dothan, Alabama. 1326 miles. Our only real issue was our 2nd trip out when I didn't level the camper properly and we had a heck of a time getting one slide back in. But since then, I've always made sure to level VERY well and we've not experienced any real issues. Little things like the Sansui television not turning on if you leave it plugged in while switching from battery power to shore power. It takes a solid 2 hours to reset for some reason. We learned to unplug it prior to switching and haven't had another issue with it. Overall I think the biggest issue that everyone else is having is their dealer and support from them. We purchased ours at the major RV dealer in Williston, VT and I can't say enough good about them. Our walk through was over 4 hours long and they showed us every single thing we ever will need to know (any some we will never need!! LOL).
As for traveling across country, my only suggestion would be to have the 2nd air conditioner installed. Before we had our 2nd unit installed, there were a number of times that the 90+ temp and 80+ humidity was just too much for the one unit. It didn't fail, just didn't cool enough to be comfortable.
Oh, and the LED strip lighting on the awnings and the blue LED on the nose will eventually start failing one at a time. It's a common problem but nothing you can't live without. Getting a new strip once enough of them have burnt out is easy and easily installed.
I hope you get this message and if you have any questions that I might be able to help with, feel free to contact me again. I'll check back more frequently! Happy Camping!

We have the 2014 version of your trailer and looks like you are one of the few happy ones. Good to know there is someone out there enjoying their trailer. We have had some small issues but mostly with slides. We are traveling for 3 weeks next year across country and are getting nervous about posts that we are seeing. Looks like you have done this before. Any advise?
