Windshield Sun Visor on A Open Trailer….

[MichaelPawelek]

Any problems with tearing up/bending a windshield sun visor while towing on a open trailer. I have to take the ‘25 Coupe some 80 miles next week and wonder what speed might have caused any damage to someone in the past. Thanks…

I would limit speed to 50 MPH to reduce the chance of damage to the visor and the rest of the car. 40 mph is better, especially under breezy conditions. Besides the force of the wind, which can easily reach and exceed hurricane force with any headwind, or when a truck passes you, grit, pebbles, and other debris will do more damage to the car at higher speeds. A passing truck under windy conditions can hit you with a pressure wave that might very well take the visor and the rest of the top off. An enclosed trailer is much to be preferred, and a trailer with some kind of wind deflector is a lot better than a flat open trailer.

I would invest in a roll of Saran wrap.

I am considering loading backwards. Any problems anyone can think of doing it that way?

[TXGOAT2]

I believe that's a better choice. Leave early. If you don't, they'll have road construction about every 5 miles.

I hauled my wife's '24 Coupe backwards on my open deck.

[George Mills]

If I'd leave a visor on, I'd load it backwards, and somehow think of a roll of Saran Wrap used judicially.

While I've seen closed cars towed at highway speeds a zillion times with no problem...I also know of one occasion where wind or something did catch a visor on its way to the show...and sardine canned peeled back the entire roof by the time he got to the venue.

On the other hand Michael, it's only about a 10 minute job to take a visor off...leave the standoffs attached to the visor, pull their screws from the front pillars...plus the 5 or so under the front roof header and lift the whole thing off. Potential problem totally eliminated.

There are many good reasons to limit speed.

Your concern regarding the sun visor is well founded. A 60 mph wind up under the visor could act as a sail and bent the frame or rip the fabric. Opening the windows slightly and wrapping Visqueen (6 mil plastic sheeting) around the visor and through the interior several passes would help provide the necessary support, especially if the plastic was wrapped in such a way as to deflect the wind down and away from the underside if the sun visor. I would mot load it backwards. Depending on the type of trailer, loading it backwards may put the heavy engine behind the tires of the trailer, lifting up the tongue and the rear ended of the towing vehicle, thus, reducing the traction, the handling and stopping ability of your towing vehicle. It is best to try and balance the load on the trailer with the same weight both in front of the trailer wheels as well as behind the trailer wheels. Good luck. Jim Patrick

All great reply’s and information!
Jim, This is a 22’ tilt trailer that I have loaded over 20k of tractors and implements on in the past so there is plenty of room to move the T back and forth for a proper balance. I understand your concern on a shorter trailer with less weight capabilities.

I hauled my '27 Tudor 1100 miles on an open trailer. I hauled it backwards and had no problems. I was running 60 mph.

Don't stop by securing the sun visor. Please store the floor boards in a safe place out of the car. Also tie the hood down, I have used a ratchet strap in the past. I lost a floor mat before I realized what was happening and then when I did, I removed the floor boards. Some may also want to remove at least the front seat as it is usually open underneath. Just my 2 cents.

[MichaelPawelek]

Dick, I have hauled my ‘19 Touring a few times over the years on a open trailer and full well know the pitfalls of not securing the floor boards, seats and folded down top. Better secured than taking any chances.

I often get my ‘16 touring up to 50+ mph while driving with the top down and windshield up. Does 50mph on a trailer present issues that 50mph under its own power does not? Yes, I know that the driver’s seat won’t move with me holding it down, but I’ve never noticed the front or rear floorboards or mats lifting, nor has the folded top with a boot on it been a problem… I have had the hood move around when I was driving with all of the latches off, but I don’t consider that to be a design problem.

It seems like the Montana 500 folks regularly go faster with stock bodied cars. I don’t believe that they use shrink wrap or cargo straps to hold them together while driving.

I've had floorboards come up and shift while driving on a windy day. The top toe board shifted and jammed the brake and clutch pedals. Luckily, I was able to coast past my gate and roll to a stop. I thought the transmission had thrashed out. As far as trailering a car, the air hitting the car behind a tow vehicle is "dirty air". It is very turbulent and very often carries grit, pebbles, bugs, etc. Passing vehicles, especialy large trucks, can cause powerful surges of air, which can combine with windage and ambient winds to do significant damage. If you are driving at 60 MPH into a 20 MPH headwind, your air speed is around 80 MPH. Thow in a blast from a passing truck or motorhome, or a 35 MPH gust, and that could top 100 MPH. That's F1 tornado territory. The ability of moving air to do damage goes up as the square of the speed. 60 MPH is much more destructive than 50 MPH. A car on a trailer may see a negative pressure behind the rear of the cabin or the back of the soft top and a substantial positive pressure on the front. That can amplify the force of wind hitting the car head-on. Best to slow down.

Load backwards to protect the sun visor, also the windshield & radiator from flying debris. More aerodynamic too
Travel time. You aren't going far enough to "make time" by going fast
70 mph = 1hr 6 min mph likely over the trailer speed limit
60 mph = 1hr 20 min 14 min longer than 70mph
55 mph = 1hr 27min 7 min than 60mph or 21min more than 70mph
50 mph = 1hr 36 min 9 min longer than 55mph but likely better fuel economy

Make that an open trailer (I know that it is inferred in this thread, but you know how things go around here)

What about wind wings on a touring on an open trailer?

[Will_Vanderburg]

Why not just drive it?

[MichaelPawelek]

Because all the roads to where it is going have a 70 mph speed limit and there is a loose magnet keeper bouncing around in the hogshead……

I trailered it 5 days ago at 60mph riding backwards on the trailer and everything went just fine.

Here is what was found when opened up.


Also none of the brass magnet screws had been peened after installing.
