MDT As Tow Vehicle

I am considering a Luxe Toy Hauler for full timing and trying to decide on best tow vehicle. I have looked at various M2 hauler conversions. My concern with that route is vs the 2020 Ford (F350/F450), the M2 has 100hp less, and similar torque, but about 5K lbs heavier. How well will the M2 actually do towing a 24K lb trailer vs a 1 ton dually. I know a MDT will absolutely outlive a 1 ton dually, but have heard they don't actually tow as well. I have also looked into an M2 112, which would give me about the same HP as the new 2020 Ford, but much more torque, and much more weight.

The M2 will have an Allison transmission with the gearing to out pull any dually. It won't be as fast off the line, but the torque and gearing will out perform the dually. Plus if the M2 is all air ride, the ride and extra height of the cab gives a better ride and view.

If you are considering buying an emergency road service, be advised the MDT will require a separate policy in addition to one for the 5er (CL 6,7, and 8 trucks)

I know this thread is a few months old, but I have the same question as the OP. Will a M2 106 get me up a mountain pass any faster than a F350/450 dually or would a M2 112 be needed?

I have a 20,000 lb fiver and a 2019 F350 dually that I took on a trip to Colorado in September and I was down to 35mph at WOT going up some of the mountain passes. Between the engine RPM’s and cooling fan noise, it sounded like it was going to blow!

I’m considering upgrading to the 2020/21 F450, but also looking at MDT’s. I certainly understand the MDT’s are much beefier and can easily handle the weight and have better braking capabilities, but with most M2 106’s at 350 hp and ~1,000 torque, will it give me anything extra going up the grades compared to the F450?

I seems to me, a M2 112 would be the best choice, since it has similar HP to the F450, but a lot more torque. I’m open to ideas.

Thanks

If you haven't seen these, TFL Truck did a series of videos on using an M2 as a tow vehicle.

I understand the idea and desire of MDT. There are lots of people that like them and they do work.

If you are in the research phase you might seriously look at HDT also. There are a lot of major pros to HDT over MDT and only a few cons.

@Rumline - thanks for the videos, I had not seen them before and they were helpful. While there wasn’t much of a speed increase going up the grade, everything else about the ride was much improved!

@Nwcid - I hear you on the HDT. The two things that give me pause on considering them is WAF (wife acceptance factor). She just thinks they are too big!! The second one is they do seem too big to use as a daily driver once you get to your destination. Sightseeing, shopping etc. In that case you may need a second vehicle. An MDT may not be any better in this regard, but they do seem a bit smaller and could be usable in this manner.

Thanks,
Alan

I fully understand all of those. Again my suggestion was for actual research on the topic. Outside of the WAF, just went though that, I think you will find HDT not that big of a difference.

Of course it depends on what you buy. If you buy a high roof, long wheel base truck it will be a huge difference. If you buy a mid-roof with a short wheel base it will not be much different in the challenges you face with driving/parking at destination. There are several online threads from people that have had both and while there are some that preferred MDT, most had very specific needs.

You did say full time, so that might mean going the Smart car route, or even having the wife follow in a separate car. It will all depend on how you plan to full time.

Yeah, these won’t climb better than a 1-ton, they’ll just do it more reliably. Climbing those passes is almost purely a hp/lb ratio, and higher is better.

Back in 2014 we went from a 2006 Dodge Dually with 610rear wheel HP (Dyno'd- a bunch of aftermarket parts and pieces) and 1000ftlbs torque to our old 1998 Volvo 610 with a M-11Cummins that is set at 400hp and 1450tq. Pulling the same 5th wheel (we're fulltime) over the same Mountain passes, the Volvo with a less HP but more Tq won hands down. More speed up the mountains, more control down the other side, etc.
With more gearing in the Volvo, I pulled I-70 westbound at 55 all the way up from Denver to the top of the tunnels pulling our old Carrilite that weighed 18500.
With the old Dodge, I won't say it struggled, but it kept hunting for the right gear, and once I lost the momentum it couldn't regain it.
