smlranger,
Yes, the roof is white. The paint only goes just up over the crown of the roof so you don't see the white of the roof. It's supposed to keep the coach cooler
, which it probably does help a little, but the FBP sucks in the heat like you don't know
. I don't think that even 30K of BTU's would do the trick in a 40 footer. Three 13.5's would more than likely work.
Also, neither RVP nor Dometic make more than a 27000 BTU package unit in the RV market at this time. RVP does have a single compressor unit that we thought about adding, but its heavier than the rooftop unit, would be more complex to install, and wasn't as efficient. It would also take up more space in the basement.
But, it's food for thought for Winnebago. Certainly, either the package unit A/C manufacturers need to revisit their sizing offerings, or Winnie needs to think seriously about adding another single unit as an option.
Cheers
