If you need a more compact unit, the Eco Flow Wave 2 or Wave 3 are fantastic. Two summers/winters on my Wave two. It heats at 6100 BTUS and cools at 5100 BTUs. Expensive, yes. However, they can run off of their own battery for 8 hours and can be recharged via solar or car charging.

I have a wave 3 that has 6800 btu of cooling. And while it can cool my van in direct sun with high 90s day. It has to use max mode to keep it comfortable. I cant imagine this would make a dent in anything over 80.

We have the same thing happening with ours that we just got two weeks ago. Did you figure it out? :(

Thank you for the honest reply! I mailed ours back today--we need ones for our doggies in the van and no way was that cutting it. We had bought a 12V rooftop AC unit but I was hesitant to have to completely rehaul our van to install it and get a proper battery bank (We power everything off of our Goal Zero right now), but looks like we are going to go that way now. Will be a big van project for this year! Thanks again!!

Only use a two hose air con with the hoses properly insulated and exhausted. I'd strongly recommend the EcoFlow Wave 3 if you want to go with a portable option but for a cheap option an RV air con installed in the roof is the way to go, I would recommend at least 8K BTU and an extraction fan. If you're staying in Las Vegas neither of those will be sufficient, you'd need 'real' air con, which is undermounted and very expensive. Source: used to use the Wave 2 now have an 11K BTU undermounted system

I used Ecoflow Wave 2 for a whole summer. Works pretty decently. The Wave 3 is even better

Budget? I'm generally not a fan of installing window ACs on vans; the lack of vertical support always seemed sketchy to me, and van bodies lack the space to install a proper support bracket like on a house. However if you are 100% sure that you will be parked and not moving the van at all for 4 months, maybe you can build a bracket to support it on the ground. Make sure to get an inverter unit, otherwise the constant bang-bang-bang-bang of it turning on and off will keep you awake at night. Alternatively, get one of Midea's hose-in-hose portable units, preferably the smaller 10,000 BTU/hr one. Use the hose outline to make a cardboard template, then cut an adapter template out of plywood and install it in a window. There might be someone on Etsy who sells one already. The most vanlife friendly (and most expensive) option would be to buy an EcoFlow Wave 3. Sure it's only 6100 BTU/hr, but it does have an inverter, can be mounted outside, and there are plenty of hose adapters available for van windows.

I tested it, and it's only really good for a specific set of people, like folks who want an easy, all-in-one off-grid heating/cooling solution and can afford it.
