We've had an AR-One going on 3 years. Yes, it is entry level. But, yes, it has everything we need. My idea of camping is spending time outdoors NOT watching tv or cooking on an outdoor kitchen nicer than the one in my house.
In the two full years of camping, we've had one small problem. The propane hose from the tank to the regulator has an excess flow valve that wasn't working right and was starving the water heater and stove. A $25 hose, for which the dealer reimbursed us for, and that was it!
I know others who love their AR-One as well. quality is good for what you pay for, it is light, small and convenient.
