That's a pretty big trailer for a single 13.5 IMHO. We got the dual AC with 50 amp service and are VERY satisfied. No problems keeping your rig cold, even on the hottest days, so for us the added expense was well worth it. We really like the floor plan and the outdoor kitchen. I think you will really like this rig.
