We spent the following week preparing for our big trip out to Elkhart, Indiana to enjoy the Silver Avion Fellowship Rally with 41, count ’em…41 other Avions! While at it…we installed a mud flap system to protect our silver beauty!!
Back story.……When we returned from our longest road trip to date (16 days) to Dearborn, Michigan this past May/June for the TCT (Tin Can Tourist) Centennial Rally we noticed that at some point, we must have driven over some loose gravel, rock chips in a construction zone because on the curbside of our Avion front area (yes, the area where Airstreams have those protective “wings”) we had a whole lot of small, tiny dings into our aluminum skin. We know these were not there prior to our trip. It is worthwhile to note that with our multiple excursions now through Pennsylvania, Ohio, Michigan, and Indiana…that the roads in those states are not nearly as good, or well maintained as ours are in NYS. So ok, higher gas taxes, and over all taxes may have some redeeming quality…but we still live in one of THE most expensive states in the union–so not much solace there.
So we have decided to purchase a mud flag bumper guard set up for our tow vehicle which is a 2011 GMC 2500 Denali HD, 6L gas, 4 WD, Crew Cab with Leer extended bed cap (which we LOVE!!).
A mudflap system would have most likely 99% prevented these chips from happening. Only sorry we did not do sooner, 46 years on the road and our baby got dinged! Not only does a mudflap protect from errant rocks coming up and hitting your rig, or worse yet, your rockguard or windows…BUT it also handles…well….MUD (snow, slush, dead animal debris, floating garbage or UFO’s on the highway!-yes it happens!) Kevin works for NYS DOT and can tell you amazing stories of what his crew finds on the highways. Mud was the other thing that washed up onto our Avion body front during this most recent trip.
Kevin got lucky when he inquired about pricing for a Rockstar Mud Flap bumper system at our favorite local after-market auto parts detailer and installer- Mac The Knife (Mac also is the one who redid our rock guard and spare tire cover- he does great work!) Mac happened to have a left over demo model of a Rockstar brand system that he had had on display in his shop a few years back. Yeah, it was dusty but Kevin got it for less than 1/2 price off current retail …and it is the same system being sold today for over $479 list. Here is link to similar set up that we have which is currently available through ETrailer.com. FYI-We have purchased several things from ETrailer.com and are very impressed with the ease of ordering online, their quick shipping and quality products. They have a huge inventory of tons of stuff and their customer service reps are very good.
Bear in mind, these things are heavy. We realized that since this will be a one time purchase for us…and when we are in our 70’s and 80’s and still on the road (don’t laugh…we will be good LORD willin’ and the creek don’t rise!) we needed the easiest way possible to lift this baby off the back hitch to store it away if we did not want to cruise around with it on the truck (it does add weight= lesser gas efficiency when not towing)
Here is a good video to show how you hook on the system to your rear bumper.
So Kevin had the idea to create a semi-permanent fix which was to affix the flap system to the receiver piece insert which then can be pulled out with the mud flap bumper system. Otherwise, we would also have to be pulling off the entire (and super heavy) GenY Torsion Hitch with the whole mudflap bumper system attached as one unit. That GenY Torsion Hitch is also a great piece of equipment and we will do a separate post just on that and cross link it here at some point.

Steps we did:
- Retro fit a longer 12″ insert reducer from 2.5″ to 2″ so that we could bolt the mud flap guard system right to that. Here is the link to the additional hardware bracket needed as well. Link to hardware sold at ETrailer.com
- Kevin used a DeWalt Saws-All with brand new blades to cut off the excess length off the reducer. Be sure to clamp down the reducer so you get as straight a cut as possible. The reducer was too long and butted right up to our spare tire, so that needed to be trimmed back by several inches. Doing this however, then threw off the alignment of the pre-drilled side holes in the reducer, making use of a hitch pin lock impossible.
- He then used several different drill bits to cut new holes in the correct positions needed to now be able to throw the hitch lock 5/8 ” pin through. It has a key lock and we have had it rekeyed to match the truck ignition so you always have it handy!
- We followed some video’s found on YouTube for the Rockstar brand installation because as we mentioned, this was a store demo unit and therefore we had no instructions or paperwork with it.
- Once installed where we knew it was properly in place, we also had to install a Heat Shield (bought on Amazon, see our link/resource page) to prevent the heat from our large exhaust pipe from damaging (a.k.a melting!) our heavy rubber mud flaps.
It is very important to have this heat shield if your exhaust goes out back before using the mudflap unit. If your pipe exhausts to the side you will not need the heat shield.
IF you are purchasing a brand new kit, you may have to put your unit together yourself. See Video As a demo model…Kevin did not have to do these steps! Ours was ready for install!

If you have any questions about this install, or why we chose our hitch or this mudflap system, feel free to email us directly at 1973Avion@gmail.com! We would love to hear from you!
Safe journeys! Share photos of your mud flap project with us on our facebook page!
