Towing speed on grade and common sense

[Taco]

I have read a lot on this forum about how fast you can or can't go up a grade with a trailer.

That is great in theory or on an empty road.

But the one common sense thing i have never recalled mentioned here is the fact that you really can't go whatever speed your truck is capable of up a hill. You usually have 2 or 3 choices of speed.

1) Speedlimit to 10 over in the far left lane

2) 35-40 mph in the far right lane with the big trucks

if there is a center lane

3) speedlimit to 5 under with the slow cars in the center lane

On a 65-75 mph highway unless you are heavily modded you can't keep pace with the left lane. On a 6 percent grade with 23k combined no stock trucks can hold 65 mph.

So that leave the option of the "climbing lane" or far right lane going 40 mph or being rude and holding up the "four wheelers".

So to put these power requirements to real trucks.

No new truck un modified should be able to haul 23k combined up a 6 percent grade at 65.

Every new 3/4 or 1 ton truck gas or diesel is capable of hauling 23k combined up a 6 percent grade at 40-45 mph.

Well not sure about that I have run 19,000# up a 6% at 60 to 65 with a slightly chiped 01 Ram about 265 HP, 600 lb. ft. Touqre. This is running 3.55 gears and a 5 sped manual. I do it as I travel many two lane roads and don't want to hold up traffic. I don't see a reason new diesel can't do that!
