Most of I-10 through AZ is 75 and trust me, if your going only 75, you’re getting passed like a Yugo on a racetrack!! I regularly run 80-85 (85 is max limit on cruise control. Just FYI) and I have no issues at all.
I have found some spots in TX that are 85. I hate the fast roads when im towing the camper, 75 is max comfortable for me. I love the 60 roads and get better fuel mpg's.
Other than eating more fuel, mine loves to go fast. Just a 2 door 4+4 tradesman. With the 2 door, I have the 28 gallon fuel tank.
( this being unofficial, of coarse) In northern MN its flat and long stretches of road. I don't know what mine did stock, but burying the needle at 120, and giving it more, the truck takes off, and no wobble, just smoooootthhh.. Ill have to check the cruse setting when back this spring, to see if it cant be set over 85.
Most wear and tear by far is slower speeds and turning. I would rather get a truck that has 200K miles going 80 on the highway then one with 100K miles of city driving or rural driving on rough roads and sharp turns.
My truck is smooth all the way up and down, but choose your stretch of highway carefully. 8K of truck at that speed does not like anything but flat autobahn type highways. We have lots of smooth roads around me, the run up to Kamloops comes to mind.
100 is really pushing it with an R speed range. I cant imagine front bearings liking those speeds and loads, or the EB when you actually need to slow down. Come to think of it, I have never used the EB to slow from a 100+ MPH run.
I’ve had this one at ~140. Surprisingly it handled it real good, till I hit a hump in road. Bouncing it a little. With solid axle steering, when front axle compresses, the steering wheel moves. Turns out, at 140, it moves a lot.
I was having fun with a buddy in a 392 challenger. Side by side till 140, he was in shock just as much as me. ( roll at 60).
Anyway, I don’t go over 80 anymore in this HD. The highways around here max at 75MPH.
The steering is not healthy at high speed on these.
I just got back from Michigan. A 1,400 mile one way trip on I 65 and I 75.
80 MPH? You'll get run off the road if that's all you're doing.
But that's about where I stayed. My fuel economy was a hand-calculated 21.7 MPG. Lie-o-meter said 23.4
My truck runs better at 80 than it does at 70.
Seems like there's a little hop to it at lower speeds. Probably the roads.
Each County hires their own contractors to work on the Interstates from what I can gather. So each stretch runs different. Easy to tell how corrupt the County is that you're passing through. They give the jobs to their Brother In Laws or some corrupt Union thugs that will funnel back much of the profits to the corrupt politicians that hired them.
Anyway, in the mountains, driving fast in that thing is no fun. At all. None. On the straights?
Hi all, new to the forum, thought I’d try this in the 4th gen section since that’s the gen i like most. Sorry for the novel you’re about to read, but here’s my question.
As of right now, I have a 2019 Ram 1500 Sport crew cab with the 6’4 bed on 33’s with 20x10 Fuel Maverick wheels on a 2”...

I have a 2015 Laramie Short Box and I'm trying to decide whether it's better to go with the Reese Sidewinder Hitch Box or a B&W Companion Slider. I'm leaning towards the Sidewinder because, in my mind, the weight of the trailer remains over the...
I am thinking about buying a Gen 4 Dodge Ram 2500 or 3500 (SRW) 4x4 to tow my Keystone Montana 5th wheel (12,500 GVWR). I am looking at all the Gen 4 years. Are there any glaring issues I should look for or certain years I should avoid? What should I look for that is good or bad? Are the Gen 4...
Just had a Thuren 2 in leveling kit installed. The garage told me everything went well except they cannot do anything to fix my steering wheel alignment because of the welded jam nuts. There was a recall on the steering link jam nuts and Rams fix was to weld them. I had thought I was told the...
