WHY? People have had the windows on their Avions blow open and get broken off of the rig when a gust of wind hit their rig while going down the road or in a bad wind storm. Don’t let this happen to you!
When we owned our 1973 Avion, 28′ LaGrande Model we noticed that one of the three prior owners had put on some “make do” hardware that held the windows more solidly closed while rolling down the road or during winter or very bad weather (rain or wind). Below is one of those “make do” clips but overtime it was only functional with our little slip of a wood shim in it! So the time to find a new “fix” was due!
CAUTION! These old Hehr windows especially the “awning type” which are the one piece large windows that crank open from the bottom out…CAN AND DO have the potential to catch a wind and fly open when rolling down the road at 50+ MPH. In case you do unfortunately lose a window or purchase a reno project Avion, Hehr does still make awning style (and Jalousie) windows and some online companies also carry a limited amount of dimensions. NO ONE in our research makes the rounded front curved windows that flank your center front window so please baby those fixed windows- we also have them in the rear bedroom of our ’87!
*note, since purchasing our 1987 32S Avion (jalousie window style) we do not have this issue with rattling or fly open accidently windows but we still make double-triple sure they are fully secured before we begin towing because if open even a little bit the wind could catch the smaller pane of a jalousie and pull it open to and strip your window crank system in the process. It seems the issues of rattling windows is more prevalent with the awning style windows found on pre mid 80’s models.
Additionally, some of our window torque operators (those little metal boxes that your crank handle fits into to raise the window out) were less than perfect, wear out quickly due to soft metal gears inside and did not always “snuggly” hold our window shut.
WHAT TO DO TO PREVENT WINDOWS HAVING A MIND OF THEIR OWN??
We purchased these simple metal “shelf clips” at our local hardware store. https://www.lowes.com/pd/Hillman-20-Pack-0-25-in-Shelf-Pins/3013872
They are cheap, come in boxes of multiples and made for a decently attractive but functional solution to ensuring our windows were all securely closed to prevent accidental opening during trailering.
We put a stainless steel screw into the pre-drilled hole and the “pin” which is intended to fit into a round hold in a bookshelf wall is actually what holds the window closed. (sorry evidently did not take a photo of this before we sold our 73 Avion!)
Part of our routine before we got underway for a trip and then when we arrive to set up at our campsite was simply to take a cordless power drill and unscrew the stainless screw to be able to rotate the clip away from the window frame to allow the window to open. We did not remove the clip entirely, merely rotated out of the way so it was ready to be deployed again to do its job once we were packing up and making ready to leave our campsite.
Last but not least….we cannot stress enough the importance of a “WALK AROUND” safety check BEFORE you tow your RV 2 feet! The walk about is Luisa’s job so there is a second pair of eyes on the hitch area and all its hook ups, etc. This Walk-Around will be where you check to see that all of your windows are secured down, if using clips like we outline above, they are engaged and tightened, awnings latched/locked in place. I will be posting a complete other “walk around” post to go into more details on this very important safety standard of practice.
Be well, happy travels!
