Thunderbird, we used queen bed sheets on the happy jack beds, and fit ok, ill have to get the measurement for the side patio, i cannot remember what they are off the top of my head. Just a few things to make sure you look at during the pdi, make sure the rear ramp door closes and fits snug on both sides at the top. make sure the refrigerator doors are perfectly aligned at the top, or the compressor will make noise. make sure the awnings roll out and back in ok, especially the big one. If your going to be using a satellite dish of any kind, make sure they hook one up and verify all the connections are good. we had 4 wires in the udc installed incorrectly according to the diagram. If you like actual surround sound, you will want to replace all the factory surround, (its very cheap) Heartland is living in the 80's using coax and rca cables to everything. So you may want to actually call and ask them to prewire hdmi cables. Will save you a lot of headache.
