The RV industry is seeing that boondocking and off-grid camping are really growth areas for all of us as campgrounds become more and more full. I’ve talked about Keystone’s Solar Flex package endlessly but now I want to look at Winnebago’s 2022 Micro Minnie FLX line, specifically the 2108DS.
FLX is Flex
Winnebago has taken a solid-selling model and “plussed” it, as Walt Disney used to say. The new FLX series incorporates a number of features that are significant game changers when it comes to off-grid usability.
The company’s goal is to be able to extend the time someone spends off grid to five days. So how did they do? Simply put – they almost nailed it.
Advanced features in the Micro Minnie FLX
While many smaller travel trailers seem to source the most low-end features, that’s not true here. In fact, Winnebago is using a number of components from Truma that are really exciting.
There’s the Truma Vario heating system, which is quite efficient. Also the Truma AquaGo hot water system that is, effectively, a tankless water heating system. You could easily blow through your entire tank of water and have it all be hot. That would be silly. But doable.
The FLX also features 380 watts of solar on the roof via two 190-watt solar panels feeding 320 watts of lithium batteries. There’s a 3,000-watt Xantrex inverter so, essentially, you can run anything.
Including the air conditioner.
AC on batteries
One of the goals of so, so many RVers is to be able to run their rattle trap Coleman Mach air conditioners on batteries – but they’re approaching the problem from the wrong side. Rather than trying to keep adding resources to feed these antiquated contraptions so many of us have on the roof, a smarter solution would be to simply employ an AC system that’s actually efficient and modern.
Enter the German-engineered Truma Aventa air conditioner. The Aventa is an extremely quiet and very efficient air conditioner. Based on specs on the Truma site, that unit consumes just 4.2 amps in cooling mode. That is literally less than one-third the power consumption of a Coleman Mach 13,500 BTU air conditioner.
This isn’t such a revolutionary concept, though. Anyone who has installed a modern AC unit, such as a mini split, in their homes know that there are ways to cool a space very efficiently.
Besides being very quiet, like a modern home AC unit, the Aventa is also low-profile.
You operate the AC and heating system from a single control panel, which also operates the water heating system.
Other stuff in the Micro Minnie FLX
The rest of the Micro Minnie FLX is pretty straightforward – but well thought through. There’s a three-burner propane cook top and a convection microwave. There is no oven, per se, but you can run the microwave off the batteries. The fridge is a 12-volt DC model.
While this is a relatively compact trailer at just 22’ 7” long and seven feet wide, Winnebago gets the most out of the interior by incorporating a single slide room and a Murphy bed system.
That slide room can be outfitted with a dinette or a jackknife sofa with a portable table.
This means you get a surprisingly large bathroom that covers the entire back of the trailer and makes for a very usable space. As Matt Foxcroft of Matt’s RV Reviews would say, this has a prime pooping position.
It’s ain’t easy (or inexpensive) being green
One thing to know: This package isn’t cheap. Winnebago estimates that the package alone will add about $14,000 to the MSRP.
I can already anticipate the comments: “I can throw a couple of lithium batteries on my RV for $1500.” Yes, you can.
But you don’t get that Truma AC unit, nor do you get the 3,000-watt Xantrex inverter, nor the total integration of all those systems. And, one more big thing. It’s all installed, working, and covered under Winnebago’s warranty.
Also, talking to a few RV companies about future product, this price is about in line with other systems, many of which are far less capable.
One catch in the Micro Minnie FLX
While Winnebago says that their goal was five days off the grid before having to come in, I will take umbrage with that in one area – the fresh water tank. My own trailer carries 42 gallons of fresh water and three days is all we can do. That’s simply because the gray tank is full after six Navy showers. That’s one shower per traveler per day, and I travel with my wife.
This does have a Showermiser system whereby the water that you’re using while waiting for hot water to reach the shower is actually diverted back into the fresh water tank. That’s a brilliant feature that Rockwood and Flagstaff have been using for years. But I don’t know if that would compensate for two more days of showering.
What would do this is to plumb the system so you flush the toilet with gray water. This would take some additional plumbing and a second water pump. I do intend to do this on a cargo trailer I’m building. I’ll let you all know how effectively, or not, this works.
Winnebago is the first company I’ve seen to make a truly off-grid trailer that lives up to the promise. Why do I write that? I’m friends with Robert Morales (Traveling Robert), who has one of these and has been testing it for some time. He has been very happy with it and he spends a great deal of time on the road – including lots of boondocking.
I think Winnebago’s approach to the problems boondockers have, by employing more energy-efficient components, means it can get by with less expensive battery systems and still deliver the experience we off-grid campers are looking for.
Yesterday I looked at Winnebago’s new Hike 100. I wrote that I think you’re doing yourself a disservice by not at least considering it if you’re looking for a small adventure-focused trailer. I think they’ve done the same thing with this new Minnie FLX series.
