Welcome to our RTS page!  Over the past several months, we have added many new and exciting items to our inventory specifically for your type of coach.  We currently have many, many more items for your vehicle than we can possibly list here.  We stock items for your air, air conditioning, engine, lighting and electrical systems, just to name a few areas. We have a significant number of body panels, ready to be put directly onto your coach!
Our BASIC PARTS CATALOG - SUMMER 2017 edition is located on our Products Catalog page and is available for download and printing from your home computer.  The Products Catalog page is located on the toolbar to the left. We are working on our newest catalog which will be introduced before next spring.
Our current newsletter is now available.  It is available at busfixx.blogspot.com. We are currently discussing air conditioning components and their function in making a good system. In addition, we have  our previous newsletters uploaded. 
We are constantly updating and increasing our feature items on our website.  Be sure to bookmark this page and check back regularly to see what we have added. Also check out our engine, generator, remanufactured components and Webasto pages.
We have many, many hard to find RTS parts in stock and ready for immediate shipment.  If you do not find what you are looking for here, please contact us by phone, fax or e-mail so that we may assist you further.  We look forward to doing business with you.
Remember to check out our home page to see our "specials". Since we change our special frequently, if you don't see something that benefits you now, check back with us. 

If you have a Webasto or Aqua Hot heating product and  are interested in learning more about them or have a nagging problem that no one seems to have an answer for, you have found the right placed to go to. We are running a special on these DBW2010 24V heaters including tray and case for $2,500.00! This price is less than half of the retail price on these units.
We are one of the oldest Webasto stocking distributors and premier warranty and repair facilities in the USA. We are knowledgeable with the entire Webasto product line and offer free technical support world-wide.

Have you ever wondered.....? If you have, we may have the answers to some of those nagging general maintenance questions.  We have added a "frequently asked questions" page to our site.  While we will continually add new questions, we are currently focused on general maintenance.  If you have a question that is not listed there, feel free to enter it and we will research it and post both the question and answer on our page.  If you have a question, many others may have the same one.  Take a minute, look at the questions and feel free to pose one of your own.
