Finding a spot for your trailer in San Diego County is harder than it should be. Many cities limit how long a trailer can sit on the street, HOAs often ban them outright, and most driveways weren’t built to hold a utility trailer, a fifth-wheel, or a loaded cargo hauler. That usually leaves two options: squeeze it in somewhere it doesn’t belong, or find a dedicated lot.
Horn Auto & RV is a secure outdoor storage facility in El Cajon, built for exactly this. We’re right off I-8, with gated access, 24/7 video surveillance, on-site security personnel, and wide turnaround lanes that make backing in a long trailer simple instead of stressful.
What we store
If it rolls and it’s a trailer, it has a home here:
- Utility and flatbed trailers
- Enclosed cargo trailers
- Travel trailers and camper trailers
- Fifth-wheel trailers
- Toy haulers
- Boat trailers
- Equipment and landscaping trailers
Spaces run from under 15 feet up to 42 feet and beyond, so whether you’re parking a small utility trailer or an oversized fifth-wheel, there’s a space that fits.
Why an open-air lot is the right call for a trailer
Covered and indoor storage make sense for some vehicles, but for most trailers an outdoor lot is the smarter choice — and it’s what we do:
- Easy in, easy out. No tight indoor clearances or narrow aisles. Pull straight in, back into a wide space, and you’re done.
- Built for big rigs. Long trailers need room to maneuver. Our turnaround areas are sized for it.
- Lower cost. You’re not paying a premium for a roof a trailer doesn’t need.
- 24/7 access to security. Gated entry, video surveillance, and on-site staff mean your trailer is watched even when you’re not around.
Being honest about it: this is open, uncovered parking. For a trailer, that’s a feature, not a compromise.
How much does trailer storage cost?
Price depends on the length of your trailer and the space it needs — a compact utility trailer and a 40-foot fifth-wheel aren’t the same footprint. Rather than guess, reach out for a current quote on the size you need. If you want to understand what drives storage pricing in general first, our guide on boat and RV storage rates walks through the same factors that apply to trailers.
Picking the right size space
The most common mistake is renting too small and clipping a fender on the way in, or renting too big and overpaying. Measure your trailer’s full length including the tongue and hitch, add a few feet of working room, and match that to a space. Our storage space size guide covers how to measure and what each size tier holds.
A few tips before you park it
A trailer that sits well stays road-ready:
- Chock the wheels and, for heavier trailers, take weight off the tires with stabilizers or jacks.
- Lock the hitch or coupler — a parked trailer is a target without one.
- Cover or seal anything that holds water, and check tire pressure before long-term parking.
- Snap a quick photo of the trailer and note the condition when you drop it off.

Frequently asked questions
Frequently asked questions
What types of trailers can I store?
Utility, flatbed, enclosed cargo, travel, camper, fifth-wheel, toy haulers, boat trailers, and equipment trailers — from under 15 feet to oversized.
Is outdoor trailer storage secure?
Yes. The lot is gated, monitored by 24/7 video surveillance, and staffed with on-site security personnel.
Why not just keep my trailer at home?
Many San Diego County cities and HOAs restrict or ban trailers parked on the street or in driveways. A dedicated lot keeps you compliant and keeps the trailer out of the elements and out of sight.
What size space do I need?
Measure your trailer’s total length including the hitch, add a little working room, and match it to a space. We can help you size it if you’re unsure — just get in touch.
