Max Towing Speed with ProPride 3P Hitch

[AZ_JOE]

I replaced my 2021 RAM 1500 Limited Crew Cab 4X4 EcoDiesel with a 2024 RAM 2500 Limited Crew Cab 4X4. My RAM 1500 EcoDiesel would drop down to 35 MPH while towing my 2023 GDRV Imagine 2600RB up 10% plus grades, and on one occasion I had to shut off the AC and turn-on the heater to keep the engine from over heating. The Cummins 6.7-Liter Turbo Diesel is standard on the 2500 Limited trim. I also opted for RAM's Automatic-Leveling Rear Air-Suspension. To prevent sway and jarring, I installed a ProPride 3P Hitch; ROADMASTER Comfort Ride Shock-Absorber System; Lippert Road Armor Shock-Absorbing Equalizers, Wet-Bolts and HD Shackles; and had my trailer tires balanced. That said, what should my not to exceed speed be towing in good weather on good roads? FTR: my TW is 800 lbs., trailer's GVWR is 7,850 lbs., and my tires are Goodyear Endurance ST225/75R15LRE set to 80 PSI.

This will be more about a drivers comfort level rather than what is a defined safe speed. Your ST tires have a max speed rating of 87mph. Your Cummins equipped truck can definitely pull it that fast. Your limiting safety factor is brakes. Up here in Canada I usually cruise about 105kmh or 65mph. On the US interstates I usually cruise at about 115 kmh..about 70mph. But it really depends on traffic. If I can't maintain a good sized buffer in front of me..I slow down significantly. I don't want to use someone else's car to help me slow down.

I have found out that with both pulling a TT and a 5th wheel, in both a 2500 and 3500, it seems the best MPG is about 65 mph, although slower would be better for mph, mixing safely with freeway traffic it is better at 65 mph. The faster you go, the MPG takes a big hit, I see almost a 1.5 mpg hit when I am at 70 mph over 65 mph, and higher gets worse "squared". Saying that, I am usually at 68 mph, as the truck/trailer combo seems to like that speed. I have been at 80 mph, and no problem, just why? Most RV truck/trailer combo's I see on the side of the road are the ones that have passed me. The older trailer tires used to be limited to 65 mph, but most now are 81+ mph rated.

I don't think whatever WDH you are using is going to make any difference as long as the trailer is loaded properly, and all your equipment is in good shape.

Depends on road conditions, ability and condition of the tow vehicle, ambient temp, your comfort and terrain. in texas the speed limit is something like 90mph, no way I would tow at 90. I tow around 70

Max speed is as fast as you can go before the TT gets loose. I have a Hensley Arrow and tow a 9200 lb TT with a Ram 3500 CTD. I go as fast as allowed under traffic and road conditions. Out by myself on the interstate I'll run 68-70. In the mtns I go with the flow.
IMO the WDH itself has nothing to do with speed. It's how your truck and trailer handle.

Thank you Scott / Wendy. Sound advice.

The sweet spot for our rig is 67-68 mph. Best mileage. Can I tow at 80, sure-but why? I’m not in a hurry.

Side note, the highest speed limit I’ve seen in Texas was 75. Not 90.

I pull our 2600 RB with a 2021 Ram/Cummins 2500 crew cab. I set my cruise control at 60-62 on expressways. I get good economy, low (no) engine noise, and the trailer tires ( GY Endurance) stay cool. Others can and do pass me, I don't really care. I'm in no hurry since I'm retired.
I'm surprised your tongue weight is so low. Mine is close to 1000, weighed with not much in the trailer.
I'm using an Equalizer E4 WD hitch with factory trailer suspension. No jarring, no sway, but concrete roadways suck.

The highest speed limit in Texas is on Hwy 130 which bypasses Austin and San Antonio. There is about 40 miles of 85mph speed limit and the rest is 80mph. My brother has had his Porsche up to speeds considerably higher than that on this stretch of highway. Texas DPS doesn't pay a lot of attention there.

Hi Jeonard -

Unless my new SHERLINE (5780) Hydraulic Tongue Weight Scale is inaccurate, the tongue weight of my 2024 GDRV Imagine 2600RB loaded is 800 lbs. with the ProPride 3P Hitch.

8,000lbs is more than the GVWR of that trailer. Just on the tongue??
I’m not aware of any frame mounted receiver that’s rated for an 8,000lb tongue weight.

I have similare set up, with Reflection. Best MPG, comfort found at 62 mph. . no sweat
