Safety and fitment

A hitch or accessory does not increase the vehicle manufacturer's towing capacity. The lowest-rated component in the vehicle, hitch, ball mount, hitch ball, wiring, trailer, tire, axle, or cargo system controls the usable limit.

Customer and installer must confirm the correct hitch class, receiver size, ball size, rise or drop, gross trailer weight, tongue weight, connector, and trailer-brake requirements. Structural modification, intensive hitch installation, suspension work, trailer axles, tires, wheel bearings, and hydraulic brake work may be declined or referred when outside verified capability or insurance coverage.

Authorized etrailer dealer

Downey Enterprise can supply trailer wiring, brake controllers, lighting, hitches, and towing accessories at dealer pricing, then install them correctly.

Customer-supplied parts are also welcome. Parts can be shipped to the shop after booking details are confirmed.

Good to know

Intermittent lighting often traces back to a poor ground or corroded connection. The goal is to repair the cause, not mask the symptom.

We handle trailer-side lighting and wiring. Tow-vehicle brake and towing systems are assessed first, and we will say when a registered repair facility is the right call.
