Richfield Trailer Supply Frequently Asked Questions

Most trailer electrical problems are caused by improper grounding. Make sure all wires are properly grounded and also check all connections including the plugs on the trailer and towing vehicle to be sure they are free of corrosion.

 The black streaks are caused by the sun drying out the rubber roof and the rain washing the residue down onto the side of your trailer. They can be prevented by using cleaners and UV protectants applied to the rubber roof two to four times each year. A black streak remover such as "Black Streak Remover" from Bio-Kleen, will eliminate black streaks that are already on your trailer.

We recommend any product containing live enzymes. We carry a variety of chemicals suited to fit your needs. Call or come in and see us.

You should inspect your hubs and brakes a MINIMUM of once a year, even if you are using the trailer only once a year. The bearings should be cleaned, inspected for pitting or corrosion, and either repacked or replaced. The races should be smooth and free of any blemishes. You should also replace the grease seal upon each inspection.

Rewire your trailer and use an electric brake controller. Electric brakes are much more cost-effective in repairs and performance.

There is no standard in the trailer industry. Trailer manufacturers use a variety of different vendors depending on availability and cost at the time of manufacture. We suggest any parts that are broken or damaged should be repaired or replaced. Bring them into us to ensure that you get the right part for your trailer.

 We don’t recommend doing this. A bias ply tire is a much thicker tire. If you are using a radial tire as a spare together with bias tires, it’s recommended you only travel with the radial spare for short trips (under 50 miles) until you can replace the radial tire with a bias ply tire. Using them together for long periods can cause uneven tread wear and inaccurate overall load rating.

No, unfortunately. Each manufacturer has over the years changed products, vendors, and manufacturing styles, and a book covering this would be larger than our store!
