D.I.Y. Projects

by Greg Zimmerman

These are projects to upgrade the looks and functionality of your 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…

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…

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…

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…

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.…

Maxx Air II fan cover

This was a terrific upgrade to our Casita.  The cover allowed us to run the fan in any weather.  We could also leave the roof vent open while in storage for air…

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…

Propane cabinet and generator mount

With grand visions of boondocking off the grid for extended lengths of time, we looked for the best option to bring our Honda EU2000 generator on trips. The Perfect Casita, also known…

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…

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…

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!…

Fix’n the Kitchen

We mostly cook outside, but here are some small improvements that make our Casita kitchen a better place to work.  The vent range and sink light were upgraded to LED.  By adding…

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…

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…

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″…

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…

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 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…

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,…

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…

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…

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…

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…

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…

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…

Electrical adapters and surge protection

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

LED RV Chandelier

At the Florida Egg and Smore’s rally, our neighbor asked me to install a neat light they had bought. It’s a Heng’s LED RV chandelier. Made in the USA, it has 4…

Mach 8 Hush Kit

Casita used the Coleman Mach 8 air conditioner from mid 2013-to mid 2017.  The Mach 8 is easy to spot from its very-low profile cover.  It’s also easy to find because it…

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…

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

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

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…

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…

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…

Shock Absorbers

What are shocks, and why use them? Every car and truck on the road is equipped with shock absorbers.  These hydraulic wonders dampen the up and down movement of the suspension while…

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…

Water Heater upgrade: Digital ignition and electric heating
