    I feel kinda dumb asking this. I have an '88 f250 centurion dually with a 7.3 5speed and gear vendors. It'll be hauling a 35 ft 5th wheel. Dont know the weight of trailer yet. Gvwr on trailer is 13,6xx. I wont run it in double overdrive while towing. What is a typical hauling speed? I was figuring 65-70. Ill be taking it south where the speed limit is 80 for about 3 hrs of the drive.

    I know to watch my EGTs, so there is that limit. I guess what I am asking is, how fast can a trailer of that size be hauled. Its a 1993.

    Most trailer tires are speed rated to 65. Not that anyone heeds that lol. I'd say look over the trailer and go with your gut feeling. Take it slowly at first and it'll tell you when it's fast enough.

    Age of the tires would also be a consideration.

    Edit. You may not even be able to get the rig too fast with a NA idi.....

    Sorry it does have an ATS turbo kit on it. I pulled it to get the tires topped off and took it for a drive and it was maxed at about 55, sense then I have removed my muffler and turned my fuel up. I havent had a chance to hook up and see the difference, but empty its not even the same truck. I really enjoy driving it now.

    this is what i consider to be the biggest overall limitation. next up you need to feel out the truck and see where it feels comfortable.

    make sure you have proper trailer tire inflation, i have seen my share of blowouts myself and with other people. trailer tires really do not seem to be made as well nowadays as they used to.

    otherwise i really like how my 5th wheel towes compared to a bumper pull camper.

    Some time recently, dot (or whoever) seems to have bumped up the st speed ratings...
    Speed
    (can my rig do 90 towing? )
    "Possibly so but" speed aint the issue, STOPPING IS.
    But you should be ok at 65-70 or so.

    The rig will tell you what speed to run. The truck has as much to do with it as the trailer.

    I pulled the same trailer with 2 different trucks. I had a 21 foot bumper tow Coachmen travel trailer. It was about 4500-5000 pounds “fully dressed”. When I bought it, I had a 2000 Dodge Durango 5.9 V-8 4x4. I had the weight distribution hitch and sway control. 60-65, in 3rd gear was really pushing it. I tried to stay below 60 if at all possible. I preferred non interstates. I traded the Durango I on my 03 Excursion (see sig). I used all the same hitch components (hitch, weight distribution and sway control). Towing with the Excursion, I crank up the A/C and set the cruise at the speed limit. The Excursion being heavier has more muscle to fight back with.... sometimes that’s more important than power......

    When I tow my bumper pull 30ft trailer with a WD and anti-sway (scaled at 7500-8000lbs) I usually run at 65mph and just wave to people as they pass me. It feels stable at that speed and it doesn't feel like I am over working the van.

    With your being a dually and a 5th wheel it will probably feel pretty stable as long as you don't have any worn parts. At the weight you are describing on the trailer I wouldn't push the speed though. I am betting that, even with the turbo kit, you will really be able to tell you have a heavy load. Plus there is the frontal area of the trailer which makes a big difference. As others have stated, towing safety is about being able to control the load and get it stopped. Except at the extremes it isn't about the power of the tow vehicle being able to pull the trailer at a higher speed.

    The best advise is drive what feels best to you. Tires tell you on the side their speed rating. I would not push that. Wind and terrain dictate how you drive also. My tires on my travel trailer are rated at 80 mph but you would never catch me going that fast. As a truck driver I have seen first hand what happens when wind, speed or blow outs destroy your camper!
