Hello there. I have an '04 Lance 921, which I bought new in Alaska. It had no air conditioner, which I did not need up there. We moved to Michigan last September, and I spent the last week baking myself alive in that thing. It does have the exhaust fan in the ceiling, but it doesn't put a dent in that heat.

Per the customer rep at Lance, they don't make the A/C unit anymore, that would fit in the roof. I have a call coming in tomorrow from the tech wizard to confirm this, but it didn't sound promising. I need something in there.

Looking at portable A/C's, they look a little big for the camper, so I see these evaporative coolers on the big box store sites. Does anyone have any experience with these? Do they work? I don't need an ice box by any stretch of the imagination, but it's almost not safe in there with these 90 degrees plus temps. Thank you for your time.

I had a Coleman Mach 8 Polar Cub installed where the standard roof vent was. Unless your roof is so full of other things there should be room to install a rooftop unit.

Evap coolers work 'ok' when it's not scorching hot, but you will notice a rise in humidity, which can feel clammy. And they need water. Are you not travelling?

I don’t know what the Lance rep is talking about , maybe he doesn’t either . Every RV roof top AC I know of fits standard 14”x 14” opening , same as a standard roof vent . The particular model that lance used back then may no longer be available but you don’t need to stick with the same model . As far as evaporative coolers they only work well in very dry climates .

Swamp coolers work great in the desert. In areas with high humidity, they just leave it hot and damp. Guess which one Michigan falls under in the summer.

You should be able to fit an aircon unit on. They aren't custom to a particular model.

We used a portable aircon on out boat for a while. The problem with a truck camper is it eats up floor space which most truck campers start out with very little. Also, you need a window where you can vent the exhaust tube. If you get one, look for the twin tube versions. The single tube uses already cooled interior air to cool the condensor, so they aren't nearly as efficient.

I wouldn’t recommend installing a swamp cooler.

The 2004 921’s should all be prewired for combination heat/AC thermostat, Roof AC, Fantastic fan, Microwave, stereo and speakers, and TV antenna whether those options were ordered or not.

Any standard non-ducted RV roof air conditioner can be installed in the roof vent opening that’s in front of the refrigerator. There should be a blank electrical box cover in the ceiling next to the vent opening, and that’s where the 115v and thermostat wires will be stashed. There may not be a breaker in the power center for the air conditioner, but the wires will definitely be there. You may also have to install a new combination thermostat.

This is what the electrical box in the ceiling looks like in my camper.

This is a screenshot from the 2004 Lance brochures the 921 interior, and I’ve circled what I believe is the air conditioner prewiring box in the ceiling.

Mine didn't come work an AC either..I priced them out and decided not to spend that much for a roof AC..I went with a 5K window unit that works far better than the roof AC I had on my last truck camper and it is super quiet compared and my little honda runs out easily on eco mode..

If you have a rear window, this is also what I would do.

I remember Michigan. Step out of the shower, towel off, then stay damp all day. If the water doesn't evaporate there is no cooling.

Evaporative coolers/"swamp coolers" do not work except 8n ver low humidity (desert SW).
