About Us

We at Sierra Engineering Co., Inc are pleased to be in our 24th year of manufacturing obsolete, hard to find, RV replacement parts. We produce identical reproduction of the original part, manufactured of fiberglass, rather than the non-reinforced material we are usually replacing. Unlike their plastic counterparts our fiberglass parts have a high resistance to sunlight, are easily repaired and will far outlast the originals.

We are continually taking on discontinued parts to reproduce to keep up with the demand for obsolete, hard to find RV parts. If you don't see it in our catalog, don't hesitate to call or send us a message. We may be adding it to our inventory.

We offer a RUSH service on our fiberglass products for $20 per part.  Ships within 48 business hours (when available) of the time the order is placed. Rush service is only available on fiberglass parts that Sierra Engineering manufactures.

When ordering please select the part from the dimensions on our drawing. We do not have all the information as to the year and model and have found that many of our parts can and do fit other makes, models and years. Dimensions may vary up to 1/2" from those listed in the catalog. On wheel skirts and trims: the left side is the driver's side; the right side is the passenger side.

Due to popular demand for some of our discontinued parts; we have decided to make many of them available again.

We're sorry but due to the fact that these parts are made to order, all sales are final. Please check your dimensions before ordering. We are more than willing to help you with any questions regarding technical assistance and/or more specific dimensions.
