A/C Roof Unit?

guttafixit · 09-22-2015, 08:36 PM

Hi, We just bought a 2002 Rockwood Premier 2518G.
I want to buy a roof A/C Unit for it. It doesn't have one in it yet. I was looking at them and I see Coleman and Dometic are the top 2 units to buy.
What would you guys buy for you'r camper if you had 1 like ours? I see they come between 13,500 and 15,000 BTU's.
I don't know much about the roof top ones but I would like to buy a combo one that puts heat out also or buy one that I can add the heat unit to it later down the road.
Has anyone done this before?
I am looking at this unit
Coleman-Mach Mach 3 Plus 13500 BTU Air Conditioner - Arctic White - Rv Products 48203C966/48203-876 - Air Conditioners - Camping World
Not sure but do I have to buy the top part (like the link above) and then have to buy the bottom part? Like >> Ceiling Assembly - Rv Products 9430D715 - Air Conditioner Accessories - Camping World

Any help would be appreciated.

Thanks, Dan

you need to buy the roof unit and inside unit. 13.5 should be enough for your unit. I believe heat can be added later, but a space heater might be a better option. Here is a better price on the one you are looking at. I just bought a unit from this place. Best prices I found. Super fast shipping. COLEMAN 13500 btu RV ROOF AIR CONDITIONER Top Unit - $487.95

Just looked at that site. Looks like I might get one there. I have until next summer to buy it. So it's a winter project for me. lol That and by a new awning.
Do I have to cut an opening 14"x14" in the roof or do I just use the vent hole? I haven't measured the vent yet to see if it's 14"x14".
Thank you

vent holes are 14x14

If you're looking for a used one, I'll be pulling one off my 2011 pup next month. (Provided you're any reasonable driving distance from PA)

Never mind. ( just saw your location in your profile). It would cost too much in gas money to be worthwhile.

Sounds like a weekend trip..

I will ask the wife if she wouldn't mind going down.
What part you in?

I will suggest the 15000 dometic heat pump. We dont think about heat until it drops below 40. The unit in our coach stays powered 24/7/365 unless we are rolling. Still 30 amp service. No problems...

If you're serious, I'm in southeast PA (Berks county, not far from Reading). (45 min NW of Philly.)

I have a 2011 pup with a 13,500 btu Coleman unit.

Works fine, but will be pulling it off after my last trip in mid-Oct so I can fit the pup in the garage for the winter. Then in the spring, I'll be replacing it with a low profile unit so it'll fit in the garage year round.

As far as price for a used unit, I'll go with the majority opinion of the forum.

If your roof vent is in the right rear of your camper, you will have to cut the 14 X 14 hole in your roof for the AC unit. The cross rails for support are on the roof center with the axel. Good luck on your install.

I will get back to you. We are going to a Pats game the end of Oct.

Standing inside faces the front of the camper the vent is on the back right. So I'll have to find where to cut a hole.
I was wondering how a A/C unit would fit that close to the side and rear of the top.
Thanks

Our a/c in our Wolf Pup is so loud that we can hardly hear ourselves talking. Anybody out there with a 2015 Wolf Pup?

they are all much louder than what you are used to in your home.

mine came with a Coleman Mach 8 13.5Kbtu
no heat strip, space heater works better and is cheaper than the heat strip parts.

the difference that i know is the Mach 8 is shorter by far compared to the mach 3 mach 8 is 8.25 inches and the mach 3 is 13.85

it works fine in South Florida in June, I can attest to that, not going to find a much hotter or more humid climate that time of year

She said it was too far. And don't think we would have enough cash to do it by then end of Oct.
Thanks anyways.

I will look into that.

I couldn't find 4 dimples (14" square") on the ceiling that would be for the ac unit. So looks like I'll have to cut the roof. If I can find a diagram of the roof bracing.
