I'm of the opinion that you only compromise a solid roof when absolutely necessary (you won't see a sunroof in any car I own). I understand the AC and Fantastic Fan vent on the TM but would have preferred to not have at least one (if not both) of the skylight vents. There are a ton of windows so light isn't an issue. Also, all these vents are so close together that it seems that some of the structural integrity/strength of the roof was likely compromised. Every hole, seam, screw, etc on that roof is a leak waiting to happen and with the middle seam, edge seams, 3 vents, AC, awning and TV antenna, it's just a matter of time. If I were ordering a new TM, I would skip the addition of the two skylight vents (if that's possible). This would also save in labor and part costs for the TM construction and reduce potential leak and maintenance trouble. Just my $0.02.

Camping in Fl I'm surprised you said that about vents. for us more is better. We have owned two TT, and a motorhome before the TM and vent leaks. Roof seams are the culprit from what we have seen.
