An Epic off-grid 2006 Keystone Montana 3475RL For Sale!

When we sold everything and hit the road in 2017, we committed to traveling until we were “done.” Well, that time has come. That means great things for you, our ideal buyer. You are into DIY, and love learning – constantly. You embrace challenges and revel in successful problem solving.

This RV has been from Acadia in Maine to San Diego, CA., the Keys, and Devil’s Tower and most everywhere in between. We learned so much while living in it, and it’s time to share that knowledge with you.

Government Wash, Las Vegas, Nevada. Very off-grid.

To start, it’s a great layout for the right buyer. It has a rear living (RL) with a forward master bedroom. There is ample storage both in the rig and under. Space won’t be a concern.

We removed the original desk and entertainment center and replaced it with a twin sized mattress, two dog kennels, and a small dresser/storage compartment. Privacy for the “room” comes by way of a projector screen, pulled all the way down.

We made every modification with off-grid living in mind. We upgraded the toilet with a Nature’s Head, and re-routed the liquids to the black tank. That gives us (a family of three) about two weeks before it needs to be emptied.

I installed a great solar system that provided two days of power without a generator or external source. That was for heavy use (two gaming laptops for example) so if your electrical requirements are less, it’ll last a good long time. If the sun just refuses to come out, we have a 2300 watt Ryobi generator with bluetooth control. Plug that into the Charger/Inverter and the batteries will be charged in no time! The system will also take power from the truck to charge the batteries while driving (it has another inverter to take 12v to 120v for the MultiPlus via pigtail). Speaking of batteries, it’s a DIY setup with two Tesla Model S modules for a total of 466 Ah of 24v Lithium storage. I used all Victron hardware (a venus GX for remote access, two charge controllers, a BMV-712, and the MultiPlus 24/3000/70). There’s an automatic transfer switch for the times you’re plugged into shore power. The rig itself is a 50 amp rig. We have a 35′ 50 amp cord with a 30 amp and 20 amp adapter.

We replaced the dual fuel RV refrigerator with a residential Magic Chef unit of the same size. The increase in space was noticeable right away, and the power savings over running the dual fuel in electric is astonishing. We had no problems with power for the fridge.

While we were in Florida we found an opportune time to replace the AC unit. It was the original (a 13,500 BTU) and we replaced it with a Dometic Brisk II 15,000 BTU unit. It does a great job – especially if you have experience in an RV with lots of windows (tip: reflectix in the windows taking the sun… we’re including coverings for every window). Before you ask, the AC will not run on the solar setup alone. You can run the generator with the solar and power it – the MultiPlus will combine power sources!

The rig is *fully functional* with the slides in. This is great for quick overnight stays on long drives, but it also means rest stops become actual rest stops. No need to put out slides to make lunch or take a nap. It just works.

A popup/flip down desk was added behind the sink, taking advantage of the dead space on that wall. It also allowed all three of us to have a working space. Remove the two legs and it folds flat against the wall with lots of room for the slide to move. There’s also a space extension for the kitchen (it’s hanging to the right).

The suspension was rebuilt in the fall of 2019, with all new parts. The leaf springs were upgraded in the process to handle 7k lbs. We recently replaced all four tires with trailer grade E1 Goodyear. It has disc brakes as well – very handy for mountain traveling. Last year we also replaced the front landing gear legs with new ones from eTrailer.

From a technology perspective, we’ve got some great upgrades. I rewired the surround sound to work with a 720p projector (it displays at about 80 inches). It’s hidden from view in the cabinets above the living room slide.

Communications are essential so we’re including a WeBoost Drive 4G-X RV (I replaced the TV antenna with the WeBoost antenna – so when you stop, you can raise the antenna for better reception!), an AT&T Homebase, and a Verizon Jetpack 8800i. The latter won’t have service, but you’ll get the hardware and you can activate your own plans. We’re also throwing in an Apple AirPort Extreme to give better 5G WiFi in the rig.

In addition to all of that, we’re throwing in a bunch of goods that make RV life great: a queen sized Zinus Green Tea 6-inch Memory Foam Mattress, a Berkey water filter system (all of the filters!), Andersen Levelers, a LevelMate Pro Bluetooth level reader, a 30 gallon fresh water bladder (for filling up wile in the boonies!), a 40 gallon plastic tote for gray and compost liquids (urine) though I’d recommend a 40 gallon bladder for this purpose. It’ll fold up and store in the basement (the plastic tote requires space in the bed of the truck right now), and a Macerator pump that will pump the liquids (remember, no solids/black water) from the tanks through a regular hose into the tote in the bed of the truck! That makes for really simple tank management. Of course it comes with the hoses and connections to make it work.

Now for the things that need attention. If you’re reading this and you’re still engaged, it means you’re probably an RV veteran, you’re “handy,” or you’re not opposed to investing some time to make the place yours. Excellent.

First, the living room slide needs two things. 1) the floor under the slide closest to the front door needs to be fixed. It’s rotted out, which makes moving the slide in and out something you have to pay attention to. And 2) the hydraulic cylinder that moves the slide in and out has a leak ($259 part). This isn’t immediately noticeable, but you’ll notice that slides creep out as you’re driving. I have a simple workaround for this, but ideally it gets fixed so you can focus your move day energy to the road.

When the composting toilet was installed, we were using the built-in tank (2.2 gallons). With a family of three we were emptying it every 24 hours. So I decided to route the liquids to the black tank. In doing so, I inadvertently created a loop between the toilet and the roof vent – the vent of the toilet goes into the original sewer vent. I bought the parts to fix this (it’s a really neat inline p trap) but haven’t made the time to install it.

We never replaced the trim after the remodeling and in replacing the refrigerator. We have all of the wood and supplies, but it still needs to be done. The closet in the master is still raw (needs paint), and some of the floors could use attention.

The ask.

This is a brain dump of an advertisement to sell this rig, but I think it’s required to come to a fair price. We know this isn’t in perfect shape, it’s old, and it’s going to require some TLC. But it’s also a beast and is able to hit the ground running from day one. Buy it, go stay in a field for weeks connected to nothing except the internet. It’s that good.

Our ask is $20,000, all in. It has a clean Texas title. Please email epicminilife at gmail if this RV rings your bell! I’m more than happy to help you though all of this. If you’ll be in the area, set up nearby and I’ll come hang out and show you the ropes.

Thank you!
