Liberty is the first converter to have a true 2010 model H3-45 in stock. It is a tripple slide with two slides in the bedroom. Looking at the pictures on their web site, I could not see the compartment for OTR. I called and confirmed that the tripple slide does NOT have OTR, because of weight. I was told they have 8 batteries and 4 inverters, which will run all 4 cruise airs, plus an evaporator in the compartment under the driver seat to cool the cockpit area, and that it does a good job. Personally, I would rather have the OTR than an extra bedroom slide. I really enjoy the OTR when travelling in hot weather.
