D.I.Y. Projects

by Greg Zimmerman

These are projects to upgrade the looks and functionality of your Casita.

Solar Port

A flush mounted solar port makes a Casita “solar ready”. A portable solar panel can be plugged in to help charge the battery when camping “off the grid”. Because the plug is…

Window Awnings

Window awnings add a touch of class and are effective at blocking sunlight and offering some extra privacy. To deploy, pull the strap to unroll the awning and hook the end to…

Toilet Supply Shut-Off

Another LHC modification is the shut-off valve.  It’s cheap insurance against a failed toilet flush valve.  If the valve fails, water will continuously run into the toilet which can result in a…

Thumb Latches for the Hatches

A popular modification is to do away with the “security” of keyed hatches and replacing them with thumb latches. Every Casita hatch as well as most other RV’s use the CH751 key.…

Bug Screens for the Appliances

Bug Screens keep critters out of the openings of the Casita’s appliances.  Mud Dauber Wasps are a particularly nasty bug that love to camp in Casitas too.  One time I opened the…

Shock Absorbers

I can no longer recommend parts from Perfect Casita/Orbital Machine Works.  They’re not delivering products in a timely fashion and their customer service has taken a dive.  If they get their act…

LED Chandelier for roof vent

This LED chandelier adds lots of needed light in a Casita. This made in-the-USA light by Heng’s is available in 4 versions: clear or frosted lens and “cool” or “warm” light.  The warm…

Battery Upgrade

It was time to upgrade the battery and I wanted more capacity without jumping to a group 31 which requires modifying the hold down (they’re really big and heavy). Trojan batteries are…

Detachable Power Cord

Upgrading to a detachable power cord has a few advantages.  The connection is weather and bug proof.  The cord can be coiled up and kept elsewhere or stuffed back in the original…

Electrical adapters and surge protection

I was a Cub Scout as a kid and now Scout Leader. I always like to be prepared, and having a pair of electrical adapters is a great idea. The 15 amp…

Outside Shower

An outside shower is an option on Casitas.  If your Casita didn’t come with one, it can be added!  The factory installs the shower box on the non-curb side of the Casita.…

Water Tank Hatch Holder

The water tank access door falls down while wrestling hoses and other gear in and out of the compartment.  There’s a brilliant little device that will solve this problem.  They are called…

Double Entry Step

Little House Customs sells a double entry step for our Casitas.  Having an extra step is great for people with mobility issues or if you have a lifted Casita. The steps are…

Mach 8 Hush Kit

I can no longer recommend parts from Perfect Casita/Orbital Machine Works.  They’re not delivering products in a timely fashion and their customer service has taken a dive.  If they get their act…

Deep Kitchen Sink

Replace the shallow kitchen sink with this restaurant quality deep sink and high rise faucet.  The Krowne HS-1419 includes a heavy duty metal faucet and a drain basket. The installation requires cutting…

Water Heater Annual Service

Every year you should flush the water heater and check the condition of the anode.  Anodes are made out of either magnesium or aluminum and are “sacrificial”, meaning that the water eats…

Full control of the A/C and heat (the hard way)

I previously wrote how to do the “A/C mod” to have a digital thermostat control the air conditioning and heat through a relay. It works well and is doable for the average…

Screened Door Pet Guard

We needed to pet-proof the screened door.  I didn’t like the commercially available RV pet grates because they had poor reviews and appeared flimsy. I settled on aluminum flattened expanded mesh.  None…

Keypad Lock

We don’t like carrying keys. Our house and garage have keypad locks. Our kids can use keypads too. Bauer makes an electronic keypad lock for RV’s. I couldn’t find anyone on the…

A/C Mod (thermostat for the A/C)

The “A/C Mod” is one of the most popular upgrades for 2018 and older Casitas. From the factory, the roof mounted air conditioner fan runs constantly and the compressor cycles on and…

Soft Start Capacitor- Coleman Polar Cub Air Conditioner

Our Honda EU2000 generator didn’t have the oomph to reliability start our 2009-era Coleman Polar-Cub air conditioner. It would trip the overload protection about half the time. After doing some research, I…

Stabilizer Jacks

Adding BAL scissor jacks greatly increases the stability of the Casita. Prior to 2019, Casitas came with single leg rear stabilizers and relied on the single front jack to hold up the…

Stove Cover Fix

The metal stove cover was rattling and wearing through the fiberglass counter top. Delicia asked what I could do to fix it. An idea immediately popped into my head. Automotive door edging!…

Solar

We installed a 100 watt solar panel on the roof of our Casita. The panel will give us enough electricity to keep the battery charged while camping and traveling. Solar alone won’t…

12 volt USB Charging Port

Having a 12 volt USB port gives us more charging options.  We can charge devices on battery (no hookups or AC power).   The lone 12v outlet for the TV wasn’t enough…

Entry Door Reinforcement/Repair for $6

Casita’s have a design flaw in that if the door opens too far, it will hit the aluminum “belly band”.  Our door already came broken courtesy of the previous owner.  It doesn’t…

Battery Disconnect

The Casita battery is wired directly to the electrical system.  Because of this, the propane detector draws constant power and will kill the battery in a matter of weeks if the Casita…

Fix’n the Kitchen

Kitchen Vent Refresh The furnace vent was showing it’s age so I drilled out the rivets (3/16″ bit) and painted it with the same Rustoleum “Heirloom White” that we used on the…

Refrigerator Hinge Reinforcement

The Dometic fridge in the 17′ Casita has a weak plastic hinge.  It can break if it pops open in transit, is overloaded, or by leaning on it while open.  Replacing the…

Gray Water Tank Upgrades

The Fast Gray Modification The Casita’s 32 gallon gray water tank is notorious for slow draining and leaving gallons of water trapped after dumping.   Emptying can take up to 10 minutes,…

Digital Thermostat for the Furnace

The first time I camped in the winter I didn’t get much sleep.  I was awake and adjusting the furnace thermostat every 30 minutes trying to get a comfortable temperature.   Bleary…

Water Tank Vent Modification

We usually tow our Casita with empty tanks to minimize weight because it’s easier to tow.  An exception is when traveling to destinations without water hookups.  In that case, we fill the…

Bathroom Upgrades

While the Casita bathroom is tiny, there is a lot of room for improvement.  Flooring Nobody liked stepping onto the wet floor in the bathroom, and any tracked in dirt turned into…

Water: Clear, Grey, and Black

If you’re new to RV’ing, you might not know about the “colors” of water.   Clear is the drinking water.  Supplied by either the onboard tank or a “city connection”, which is…

Flooring Makeover in 1/2 a Day

Our Casita thankfully came with the optional vinyl sheet flooring, but it was showing its age and had mystery rust stains.  After some research, we settled on Traffic Master stick down 12×24″…

Ground Tackle

Essential for our Casita is ground tackle (nautical term from my Navy days). For wheel chocks, I have 2 types.  At home or in storage, I highly recommend rubber wheel chocks over…

Maxx Air II fan cover

For 2017 and older Casitas with the Fan-tastic vent fan, this is a “mandatory” upgrade. The cover allowed us to run the fan in any weather.  We could also leave the roof…

New Cushion Covers

Even though our Casita is a 2009, the interior was stuck in 1990.  Tamara Armstrong at Clifton Upholstery in Waco, Texas (she doesn’t have a website, but you can email or call her:…

Painted doors and Birch plywood table

We (and by “we” I mean Delicia) didn’t like the oak-look laminate doors in our Casita so it was time for a makeover.  We (I mean me) also had a new dinette…

Calmark Cover

Since our Casita lives outside at a Coast Guard station air field in the Florida weather, I wanted the best protection I could find. Calmark makes their covers with “Sunbrella” which is…

Kitchen Vent Upgrade

The old style kitchen vent had turned yellow and looked dated.  Newer Casitas use the JR Endura vent which looks better, and has better latches to keep it closed while trailering. Upgrade…

Water Heater upgrade: Digital ignition and electric heating

Why start off simple?   Our first project was also the most difficult. When we purchased our Casita, the water heater was disconnected by the prior owner due to a leak. The…
