My feelings about Montana are mixed. Although, I've had my share of problems with my 2011 3455SA 5th wheel, my biggest complaint is the amount of time my rig is in the shop waiting on a part from Keystone. It's been a nightmare getting a standard part from Keystone. I've had consistent slideout problems. Very frustrating when you have trips planned and can't get parts in a timely fashion.
