Roof A/c water inside normal?

Well down in Florida it's blazing where I am and had the roof unit running quiet along time notice water droplets blowing out of the vents thought dang my a/c roof seal must be leaking pulled off under covers to check and behold to me surprisingly the outer edges around the unit was bone dry??? The water appeared to coming down from the blower hole area? Could I be creating that much condensation? And I mean it was enough water that when I pulled the cover off it dripped pretty good sop is this normal?

Absolutely possible since you are in hot and humid area. I've had that happen to me here in AL. I use 2 Damp Rid hanging things from Costco to help lower the humidity inside the coach. It really helps! These ac's recirculate inside air and don't pull air from outside. Every person adds water and every door opening adds water. I haven't had a problem since using Damp Rid.

Here in Louisiana I have issues with condensation forming on the air register nearest the door (also nearest the air conditioner unit), although thankfully dripping is minimal.

Ahhhhh that explains the extra vent on the units I guess that's the suction

It's not unusual in high humidity regions, especially if the coach is not well sealed (e.g. air gaps around slides), or simply when people are opening the door frequently. Cooking also releases a lot of moisture into the interior air, as do a bunch of people simply breathing. Unlike a residential fixed a/c, there is no inside pan to catch any condensation droplets that might form. I've also seen condensation for on the duct outlets in a few rigs on really muggy days.

Yup, you've got a condensation problem for sure! You're not running the fan on low are you? I would think that running the fan on high might reduce it!

Down here in south TX, near the coast, we have a regular dehumidifier in the MH and it is more than capable of filling its bucket twice a day. You may feel that the Damp Rid helps you, but if you look at the specs for how much water it can actually absorb you'll find that it is literally a "drop in the bucket" compared to how much water a "real" dehumidifier can remove from the air.

How big of a dehumidifier do you have?

It's a small Frigidaire and I think it's rated at ~30 pints a day. It makes a huge difference in the coach; the A/C can be set a couple of degrees higher while still retaining a comfortable living environment.

Thanks docj !! I will definitely look into getting one. Never really thought about it but I can see where it would help. Coming into the summer camping months in South Louisiana I know exactly where you are coming from.

We have a spot for it just behind the passenger's chair where it fits without affecting the chair's ability to rotate to the living area. All we had had there was a basket of magazines which were easy enough to move. We hadn't thought about it either until one of our friends mentioned he had bought one.
