I have the 154BH with 5000 BTU wall unit. It has performed well on days in the 90s.
I have a 184BH (2013 MODEL) It does a fairly decent job in the summer. We had one trip at Cedar Hill State Park with no shade and it was 110 outside. Unbearable outside. 85 inside. Not as cool as you want, but then again.. you're camping! It ran on high constantly.
I went out to check on my 184BH tonight (Supposed to freeze here in North Texas) I noticed that my seat cushion (driver's side dinette) was wet underneath vinyl side against the plywood. This is my first RV. In the center of the seat. There appear to be no leaks. Could it be condensation? Very strange.
thanks for the reply. I was able to go and look for leaks while a steady rain was occurring. Still dont know the exact source of the leak but I am betting on it being the front window. Will try to attach pics when I figure out what I am doing wrong.
