A sudden loss of air in a front tire at 80 wouldn't be much different than 85! Things would get a bit hectic for a while.
I always take care to have good tires, check them before each trip and watch the pressure closely. Keeping one eye on the dash while letting it run on a hill is the reason I noticed the warning come on at 80 now when it used to come up at 85.
Happy Glamping.

I agree, a sudden loss of a front tire air pressure in a MH at 80 or 85 mph would not change the outcome results. It would most likely be the end of the road/life for all on board!

I agree with previous comments on driving that fast especially down grades. The brake systems are not the best on some of these gas coaches. I always gear down going down grades and keep the MH at 60-65 max while towing a car on the level. Also your anxiety level increases with speed and wears you out over time. My anxiety level goes up more coming down a grade than going up. With that much weight pushing you, if something comes loose (rotor explodes, tire blows, etc.), you will wish you were driving 45-50 mph or under. I guess after driving commercial trucks for 30 years, I've seen a lot. But that's just me.

What likely you have seen is a lot of poorly maintained vehicles. Nothing fails without cause.

No, I havenít seen a lot of poorly maintained vehicles since I own the fleet and could lose my business over that. What I have seen are crazy drivers driving large trucks, travel trailers, 18 wheelers, etc. too fast and seeing them over turned in ditches. Commercial truckers have to do daily vehicle inspections, major inspections every 6 months, and are randomly inspected at weigh stations on major interstates, all in the interest of public safety. So poor maintenance isnít as likely as someone with a regular drivers license buying a recreational vehicle thatís used a few times a year. Thereís a lot more on the line. Like I said previously, pushing 22,000 pounds down the road at 80-85 mph (not including a random wind gust) is a disaster waiting to happen.

Plus 10
Over the years I have seen statistics on roads that had the most wrecks in a state.
Or sections of roads.
Surprisingly, many were long straight sections in the plains states.

In the 60s loveland pass was a high crash section.
Monarch pass also concerning mountain driving.

Untill the roads were improved.
Snow
Ice
Weather conditions
Wind.


Not always poorly maintained vehicles.

If you want to drive 80, at any time, have at it.....just stay away from me......that kind of recklessness borders on insanity, and I prefer to no be anywhere near when the catastrophe happens....oh, by the way, thanks in advance for the traffic jam.........

I have a Class 1 licence, and have worked my entire career on heavy highway and logging trucks. That includes doing a lot of test driving, including B trains up to 140,000 pounds at highway speeds.
I am very aware of the mechanical condition of my vehicles, including the tires.
As far as letting my rig run up to 80-85 mph, it feels very solid. Also it really isn't that fast because the speedo is off around 10%. An indicated 80 is really only 72 mph, and I'm sure many have gone plenty faster than that. That is the reason I am concerned that the top speed limit has dropped from 85 to 80 mph.
Happy Glamping.

Did you ever get the build sheet for your coach. As mentioned before I am fairly certain your chassis' ECU was always equipped with the 80 MPG speed limiter. Unless that code was remapped out of your ECU some time in the past I can't imagine it not be there. Do you have an ECU remapped by Brazels or Banks or someone else?

I am confused by your statement that your speedo is 10% off. 80MPH is really 72MPH. This seems strange. The speedo's on both of my Workhorse chassis' motorhomes are dead nuts accurate. There is less than 1/2 MPH difference between my speedo and any of the several GPS units I use. I wonder how your speedos got so far out of whack?

Hi Tom,
I have the Banks ECU program in my rig now. But the speedo was off right from the time I bought it, coming up 3 years ago in April.
No, I didn't get the build sheet, but I am pretty sure it must have the top speed limit like yours, it's just odd that it was 85 for a while.
I can live with the 72 mph actual top speed, but it just seems weird that it would change.
I always have to figure in the 10% factor if I want to figure out my mileage.
I just wish it was as easy to change the speedo calibration as it is on the trucks. We would just simply go into the adjustable parameters and change the PPM (Pulse Per Mile) setting to what was needed. Like when changing diff ratios or tire sizes.

Norman

We can make speedometer error corrections on the ECM. We see a lot of 06-07 W-series with speedometer errors, apparently Workhorse did not provide the proper PPM info to GM when they were calibrating the ECMís off the assembly line.

That would be great! Next time I am in your area, could I drop in for a reset of my PPM? Or do I need to make an appointment ahead of time?

If you ever hit 80 MPH again do us all a favor and set the cruise control. That way when you crash and burn the accident scene will be on national TV and we can all have a look.
