We've got a 2013 343RL HC which we purchased in April of this year.
Had a 1000 mile shakedown cruise from our home to Zion National Park in May.
In June we left on a 9000 mile two month long trip once around the U.S. We called it "Monte's 1st Big Adventure". Everything worked great except for three glitches, only one I blame on Keystone:
1) I tweaked the 5th wheel hitch head because it wasn't properly installed. Bent some metal, but had it repaired in Council Bluffs, Iowa by
http://councilhitch.com/ a phenomenal company.
2) our Cummins-Onan 6500 generator blew a circuit board after just 14 hours of use. The folks at Cummins-Onan in Omaha, Nebraska
http://www.cumminscentralpower.com/ were great in fixing replacing it. Plus they had free onsite full-hookup camping while we waited for overnight shipping on the replacement board.
3) just 300 miles from home, 32 miles outside of Kingman AZ one of the four trailer tires blew. Did $2K worth of damage. Switched to LT tires and now feel much better

Every night we spent in the 343RL we had to pinch ourselves. We couldn't believe how great it was, sure beat our previous travel trailer - and at one time we thought that was the cat's nuts!
