We have a 2012 343RL and am glad we decided to go with it. A large reason for us going to the HC was the lighter pin weight on my 2500HD... Trucks pulls it like a dream and with airbags there is virtully no chucking... It chucks somewhat when I've left the bags at 10 pounds.
So far because I'm still working for another 523 days, 23 hours, 10 minutes we've used the trailer for several weekend trips and on my vacation for 6 weeks where we spent about 32 nights including a trip to Jackson WY from Calgary. We plan to use it for a month here and twon months there when I retire.
We wanted a King bed but it's not available in the HC so we're stuck with the Queen... It wasn't a biggie but it would have been nice...
With that said after 40 nights.... I can see why only a queen is available... With the separate bathroom it takes space from the bedroom so the bedroom is a bit small.. (I can see why the 3400's have the shower and sink in the bedroom now)
DW loves the kitchen... we opted for the double door fridge....
Ordered it with slide toppers and am glad I did... The main slide topper will pool water when it rains which is a pain to drain unless I bring in the slide...
Oodles of storage throughout this coach...
Basement doors didn't come with slam doors.... I ordered the trailer in February where the dealer ordered another identical trailer at the same time... They both came in together as 2012's where the other one came in with slam doors... mine didn't
We're elated Keystone did away with the two tone cabinets in the HC...
Some problems (as expected) at first... The day after I brought it home from the dealer some 450 miles the funace quit.... None of the Keystone warranty dealers here would lok at it for at least 2 months when they found out I didn't buy from them... Keystone came to the rescue and authorized a mobile repair who replaced the defective curcuit board a couple of days later...
Motor on the rear jacks came disengaged on the second time out... the problem was in quality control where the motor was attached to the mount with self tapping screws and the pulled themselves out. I fixed it myself by replacing them with the proper machine screws...
Cable slides seem to be fine... except for the main slide is in need of adjustment where I have an appointment at the end of the month to get them adjusted.... Keystone came through here too because I was outside the 90 adjustment window by a month and they still authorized it under warrantee....
