Being slow on upgrades can be due to being heavy.... which is not necessarily equivalent to being overweight.

Sure, but what I don't understand if why a fairly modern truck can't pull a full load up a long grade on an interstate at more than 40 mph. I remember trucks 50 years ago that couldn't do it but that was 50 years ago.

Yes but trucks 50 yrs. ago did not have gear ratio or transmissions that are in big trucks 50 yrs. ago trucks did not go as fast also trucks today are geared to run 80 mph plus. so long grades they have to run lower gears, that means slower speeds.

The engine may be worn down, there may be a transmission problem and the most likely reason is a truck loaded too heavy for its drivetrain. The driver may have missed some gears, the turbo may be shot, etc, et al.

Specng a truck is a science. Almost a specialty. Nothing at all like buying a pickup. Second or third owner may be doing work quite different than the original.

When hauling up a steep grade it is all about horsepower. A certain amount of work must be done, foot pounds of potential energy must be gained. How fast this can be done is a factor of the power available and the load.

I just reread this whole thread. Very interesting. It sure shows the entitlement mentality some people have. If I were to take one thing from it it would be something like: Don't bother me when I'm out there on the road. Don't scare me with wind blasts from big trucks, don't tailgate me while I'm putt putting along well below the speed limit. I already have white knuckles from doing this as I'm mostly a neophyte at this trailer stuff and am scared. Never mind that I'm clogging the road, interrupting commerce, slowing other people's commute and generally being a nuisance everywhere I go. Never mind that I'm unsure and therefore probably unsafe. Just stay out of my way and don't look at me as you pass. Now before you all jump on me for this post I will have you know that I think you have every Right to be out there doing your thing on the highways and byways of America. But I sure do hope you all know what a nuisance you are and how doing your thing puts a lot of people out. When I go up to my land I take US 169 around the west side of Mille Lacs Lake. It is marked as a scenic route on most maps. But I just want to get there as I've made the trip about 400 times now. It's a two lane road so the speed limit is 55. I just wish the campers and MoHos would do 55. Or 45 even. Have a thought that not everyone is retired or on vacation. Not pretend that they are the Only ones on the road.

I've driven 169 north only about 10 times. It is very pretty around huge lake Mille Lacs and on to Atkin, Grand Rapids. If I was pulling my Airstream I may have to slow to 45 around some of the curves. And I wouldn't be able to pass a slower moving truck.

I do try to pull over at safe spots to let others pass. I think that is proper etiquette RVers should have.

I can usually make speed limit on secondary roads. But I limit myself to about 62 mph on the interstates and divided highways. With the new 80 mph limits, I find my 62 causes some vehicles braking hard or even "pop their chutes" when coming up behind me.

I started this thread wondering if there were other interstate users who felt being 20 mph below the speed limit was a safety concern.

Ultradog - ironically some part of what you are saying sounds as you expressing your own entitlement? I fail to perceive many people expressing entitlement or no regard for others but I may be reading things differently

Perhaps you could provide an excerpt of what you were picking up on?

Don't bother. It's a trolling post.
