I received my part today. It is an exact match to my 1990 Ford E350 Econoline 26’ Fleetwood Jamboree. I thought it might be close but I was not expecting it to be identical. Thank You so much for having such parts. I spent many hours if not days searching the internet for such a part. It fits as good as it looks. 

Sincerely,

Wow! Just what this old RV needed. Way better than original skirts. I got everything a week earlier than expected and it fit perfectly. Please pass on to your entire team my thanks. I hope that I don’t need any more in the future but I will pass on to anyone who asks where I got these beautiful pieces. You are welcome to use this review. I added some before and after pictures for your use too????

Kristen,  

 

I just wanted to reach out to you guys and tell you I received my double axle tango trailer fender today and wow!!! It turned out amazing. I was a little worried to order two just because of the “generic” ones I ordered that didn’t work anyways were garbage. But your guys did not disappoint. Your communication with shipping and tracking was on point as well. America needs and is lucky to have companies like you guys out here right now. As soon as I save a little money I’m gonna order one for the other side.  

Thanks again, Alex 7/20/2020

Hello Sierra Engineering, 

I received a Fiberglass Rear Cap for my Jamboree yesterday, like 4 days ahead of schedule.

I am kind of picky about stuff. It was really good quality. Better than the original. It will be a pleasure to install it.

Thank you so much!!

Received the Alfa wheel well trim and was here Friday and was to be here on Monday the13th. Great timing and in excellent condition. Description says will fit 05 and possibly others. Mine is an 02 and is same size but Is of better quality than what was there. About twice the thickness of original. Extremely satisfied and customer service was great. Thanks.

Thank you so very much for the amazing fender skirts you custom made for my 1977 Road Ranger. As you can see—they are PERFECT! 

I had spent a week online trying to find some modern fender skirts that would work for my vintage trailer. I ordered and returned two different sets. I called one company and their entire team couldn’t find the right ones in the right color either. 

You were wonderful to work with and produced a high quality product that exceeded my every expectation.  Thank you for a painless and seamless transaction. 

 

Warm regards,

Thank you so much for the fender skirts! So much better than the other company I bought from in Canada. Theirs were cheap plastic. Your fiberglass replacements are so much better, and made in America! Thanks again for all your help, and for the 15% military discount.

Hi Kristen.You helped me pick out some fender skirts for my trailer and helped me pick black or grey.  I just wanted to give you some feedback.  I thought these fenders were going to be like the cheap crappy plastic ones that came on the trailer when I bought it.  But to my pleasant surprise, they are made of fiberglass, are very strong, and look great.  So THANK-YOU VERY MUCH to you and your team.  I'm very happy with these!  

Tim S. 7/29/19


Thank you for a good product. Your product put the original fenders to shame.

I just wanted to thank you for providing a better than OEM Fender Skirt. It is an exact duplicate but much better quality.
Please Thank the rep that I spoke with when I was asking questions. She was awesome on helping me place the order. I will be referring you to all my RV friends when it comes to replacement parts.
