Small trailers live or die by the details, and the 2026 Casita 17′ Spirit Deluxe has plenty of practical ones. The walk-through in the video at the end of this post (from the manufacturer) shows a trailer that keeps the familiar Casita layout, but cleans up a lot of small issues that matter on the road and at camp. It also makes clear what is standard, what is optional, and where the 2026 model got meaningful updates.
Exterior features that matter at camp and on the road
Up front, the Spirit Deluxe starts with a standard 2-inch coupler, safety chains with C-clips, and a 7-pin connector for the standard electric brakes. That means the tow vehicle still needs an electric brake controller. This trailer also had the optional electric jack, which includes a manual override, plus two 20-pound propane bottles with an auto-changeover regulator, a bubble level, and a standard solar-powered exterior light. Solar power exterior lights are so smart! I am surprised we have not seen more of these.
Along the side, the screen door, frosted entry window, grab handle, and outside 110 outlet are standard. Keyless entry is gone for 2026, so Casita moved back to a two-key lock setup. The optional 15-inch aluminum wheels come with upgraded Goodyear Endurance tires, and there is still a Zerk grease fitting behind the hub for the bearings.
A new pass-through port can route Starlink or coax cable. Also smart!
The larger fresh water tank is optional, and the storage area around it remains small but useful. Standard scissor jacks, a locking fresh water fill, sewer hose storage in the bumper, a spare tire, optional 150-pound rear receiver hitch, detachable 25-foot 30-amp power cord, solar plug-in, city water hookup, and optional outside shower round things out. Tank sizes are 15 gallons for black water and 32 for gray. The standard freshwater tank is only 15 gallons; however, there is a 25-gallon tank upgrade offered.
Awning setup and exterior updates for 2026
Casita spent time on the awning because it still trips people up. The crank goes in first, the awning rolls out a few inches, then the support legs drop before the awning extends farther. It can be done by one person, but the legs need support as it opens.
The big warning: This awning is a sun shade. It should not stay out in strong winds or bad weather.
On the body, buyers can still choose the all-white look or the gray-bottom gel coat shown above. The bathroom window is now a larger optional window, and the standard sliding windows got a more secure lock for 2026. Timber Trail decals are available in black, blue, or gray.
Interior upgrades, kitchen options, and sleeping space
Inside, this trailer has gray cabinet doors and gray wall material, though Casita also offers oak cabinetry and a lighter “sand dune” wall finish. One of the biggest changes is the cabinet hardware. The old push-button latches are mostly gone, replaced by flip-up doors with pinch locks. The Maxxfan now includes a built-in light and a shade.
All refrigerators are now 12V. This one has the optional 4.3-cubic-foot fridge with a separate freezer. It also has a microwave cabinet with a 110 outlet, optional propane furnace, optional propane cooktop with self-igniters, and the optional deep sink. Above the cooktop, the Furrion vent fan recirculates through a charcoal filter instead of venting outside.
In the back, the main bed is a full-size 76 by 54 inches. Standard cushions make the bed, while an optional 9-inch pillow-top mattress is available for owners who plan to leave it set up full-time. The rear still converts to a dinette. Under that area, the lithium battery now sits inside the trailer, and Casita says the floor is now all-composite Kay-Cel construction with no wood.
Bath, controls, and the small details that add up
The bathroom sink is now standard for 2026, though it can be left out by request. There is also a chrome shower faucet, dry storage under the sink, a halo light, and a standard fan. The main control panel can run all interior lights, and each light still works on its own switch. A voltage meter and USB ports are built in, with one blank spot left for a future 12V add-on.
The fuse box handles both 110 and 12V circuits, and the converter auto-detects AGM or lithium battery type. The water heater bypass remains easy to reach for winterizing. The TVs now need Wi-Fi because Casita no longer installs digital antennas.
Final thoughts
The 2026 Casita 17′ Spirit Deluxe looks like a tidy year of smart fixes, not a total redesign. Better window locks, better cabinet latches, inside-mounted lithium battery placement, and standard features like the bathroom sink make this trailer feel more sorted.
For anyone comparing small fiberglass trailers, this one keeps the classic Casita formula and improves the parts that owners touch every day.

Reading this article and seeing that this trailer has only 15 gals of fresh water holding tank keeps this trailer from being a smart option for a small trailer in my opinion. Most small trailers these days usually come with at least 32 to 39 gals of fresh water holding tank which make them smarter for a week long stay at a site with no fresh water hookup. This trailer would be out for me
I agree, it was one of the factors that Xed it from my list.
