How fast do you usually drive?

As a Free Wheeler (traveling alone with only one set of eyes watching the road), I find that my perfect speed when towing either the Airstream or Argosy is 55 MPH as it gives me a greater cushion when the unexpected happens. It also pays dividends with my fuel economy - - 10-13 MPG with the Overlander (6,100 pounds gross weight) and 12-14 MPG with the Minuet (3,100 pounds gross weight) - - This keeps the RPMS between 2,200 and 2,500 most of the time, and allows for use of overdrive nearly 90% of the time (Suburban with 7400 VORTEC and 4.10 differentials). With the 29-year-old Cadillac, it is more a matter of trying to limit the stresses applied to a chasis that has seen nearly three decades of use and 120,000 miles - - towing or solo, it seems to always average 8-9 MPG. I also tend to avoid Interstates as I don't like to "count miles" when I am on vacation.

Murphy of "Murphy's Law" fame seems to be continually looking over my shoulder is another reason for my caution. I have experienced such incidences as the sudden departure of the spare tire from my vehicle, and an electric tongue jack that decided to try to become a "pogo-stick" as we traveled down the highway to name two of "Murphy's" happenstances.

Conditions: Cold weather conditions, light wind, clear roads

We regularly drove anywhere up to 75 mph feeling rock solid, borderline forgetting that we were towing a trailer for the first time.

But a few times we creeped up to 80 mph (empty highway, daylight, Montana) and we began to experience swaying. Mild at first, then progressively more noticable if I tried to stay at that speed. Upon looking at the exterior mirrors and seeing the swaying, I immediately eased my foot off the gas, and felt I'd been politely informed by the trailer what speed he was happy with.

It's starts to get freaky when you feel the tail starting to wag the dog, I don't reccommend it. So when your trailer starts to shake his head "no," you'd better listen.

I've found 60 seems to be the most comfortable speed for us. The van doesn't really have towing gears in it, and that seems to be the most comfortable speed for it. The engine sounds pretty easy going there. Above that I feel like emergency manuvers might be a little dicey too. And we're usually not in a big hurry anyway - after all, we're on vacation! I like to see what's going by along the roadside

be aware

Our WBCCI chapter had a recent pitch by a trailer tire expert who told us that trailer tires are rated to run at a maximum of 65 mph. Beyond that, you are on your own.

That suited me fine since I run at 60 to 65 mph except briefly when passing.

The Duramax gives me 15 mpg at 60 and about 14 at 65. RPMs at 60 are about 1900 and it takes a substantial hill to require a downshift. The trailer is perfectly stable at any speed, but I see no compelling reason to go faster.

When towing, I go about 2 clicks BELOW the limit; thereby giving me the whole road ahead to myself.!

When I first started to tow, I was doing around 55mph. Now I'll look down at the speedo and I'm doing 65mph.

Funny how your confidence level increases with hours behind the wheel !

Average speed has been around 55mph..Once in awhile, to climb the "hills", I'll get it up to 60 or 65 mph..that abt it..
I like to enjoy the ride and, since I'm usually by myself..I gota watch out for "things" on the road..
In all candor,
I bought my Airstream to slow down and, enjoy life~I don't feel the need to "join" the traffic rush hour madness...

speed and MPG

I posted this on the other thread, but will give a fast rundown here as well.
I live in South Florida (read tabletop flat), and did some reasonably good experiments.

My Truck usually gets 14 MPG not towing.
Towing our Argosy, we got:
60MPH=11.5 mpg
65mph=10.5 mpg
70mph=8.9 mpg
75mph=7 mpg
Plus, over 70, and the trailer started wobbling and bobbling a little bit in the wind.
So, we tow between 60-65 mph, as traffic conditions and speed limits permit.
Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.

The 2000 454 powered 3500 got around 9.5-10.5 MPG towing 65-70 mph, dropping to around 9.5 mpg at 75 mph towing my Airstream.

The new Duramax powered truck has only pulled her once, and I got 12.8 mpg, but this is when the truck only had 670 miles on it.
Leaving for Florida later on this week, will report on what I get later, when I am destinated.
