Can a Deuce tow a Deuce on a trailer without a CDL ? Nope Guess not
I can see the heads shaking now
Watch me pull a rabbit from this hat (said the moose to the squirrel).
Reference the attached diagrams. The first is from the Washington state DMV and it is a matrix for determining if you need a CDL based on the Federal rules so it should work pretty well for any state. The second is from the Tranportability TM (55-2320-209-15-1).
I'm going to round up the weights I use in this example, because it makes things tougher and the example less likely to work.
We have :
a) towing Deuce ww (14,000 pounds)
b) 25+5 trailer RATED for 10,000 pounds with lunette ring (two 5000 pound axles situated as far to the rear as possible - this last part is going to be important - or even better a single 10,000 pound rated axle). Empty weight of trailer is 4000 pounds - each axle weighs 1000 pounds + deck & lunette are about 2000 pounds. (Most of the trailers I have seen advertised this size actually spec out at about 3000 pounds, but I'm leaving a lot of room for adding ramps, chains etc)
c) recovery Deuce ww (14,000 pounds)
d) all tires well over needed weight rating
First, we stop at DOT weigh station on our recovery trip. Empty trailer. Tongue weight is about 1000 pounds.
DOT guys weigh axles (from front to rear) :
#1 - front Deuce axle - 7000
#2 - front rear Deuce axle - 4000 (3500 + 500 half the tongue weight from the trailer)
#3 - rear rear Deuce axle - 4000 (3500 + 500 half the tongue weight from the trailer)
#4 - trailer axle - 3000 (4000 - 1000 pounds transferred to the Deuce pintle hitch)
Combined gross weight = 18k
Now lets look at the CDL issue. Follow the bouncing ball -
WA State Licensing: Vehicles requiring a CDL
1) Combo vehicle ? YES
2) GWR of trailer over 10k ? NO
3) GWR of tow vehicle over 26k ? NO
4) 16 people, school bus, hazmat ? NO
STOP - YOU DON'T NEED A CDL.
Now we recover our new Deuce, when we load it on the 25+5 trailer we position it so that the center of gravity (CofG) of the recovered Deuce is placed pretty much on the midpoint between the lunette ring/pintle hitch and the center of the trailer's tandems. If the center of the trailer tandems is 2 feet from the rear of the trailer (remember from above that we put them as far rearward as possible) then it is 28 feet (25 + 5 - 2) from the center of the trailer axles to the lunette ring.
The CofG of the Deuce is about 7 feet (85 inches according to the diagram from the TM) from the center of the front axle - approximately in line with the front of the bed. So we mark the trailer bed at 16 feet from the rear of the trailer (half the 28 feet + the 2 feet for the tandem center). This puts the front axle of the recovery deuce about 2 feet from the front of the trailer deck. The front of the deuce would then overhang the lunette frame about 29 inches (53 inches - 24 inches) - not sure if this would cause problems or not - if it did, you just need a trailer with a longer deck so it didn't overhang as much.
Now we stop at the DOT weigh station on the way back.
Because the deuce CofG is at the midpoint between the lunette and the center of the trailer tandems, this should result in 50 percent of the recovery Deuce's weight being transferred to the tongue weight and 50 percent ending up on the trailer axles. Now the scale shows the following weights :
#1 - 7000
#2 - 7500 (4000 + 3500 1/4 the recovery Deuce)
#3 - 7500 (4000 + 3500 1/4 the recovery Deuce)
#4 - 10000 (3000 + 7000 1/2 the recovery Deuce)
Tow Deuce weight = 7000 + 7500 + 7500 = 22,000
Trailer weight = 10,000
Note that the total COMBINED weight is now 32,000 pounds BUT we have not exceeded the RATINGS for our tires, nor any of our axles, NOR the weight ratings for the tow Deuce or the trailer. The trailer at 10,000 pounds is pretty much right at the limit, but adjustments could be made to get this a bit lower for more wiggle room.
NO TICKETS FOR BEING OVERWEIGHT.
Now we go back and look at the CDL issue again - since whether or not you need a CDL is based on the RATINGS for the tow vehicle and the trailer - nothing has changed.
1) Combo vehicle ? YES
2) GVWR of trailer over 10k ? NO
3) GVWR of tow vehicle over 26k ? NO
4) 16 people, school bus, hazmat ? NO
STOP - YOU DON'T NEED A CDL.
There's your rabbit.
BTW - I got the information for creating this example from a forum where someone who has gone thru hundreds of DOT weight stations all over the US has done something just like this, regularly exceeding 26k total weight, while staying UNDER the CDL limits. I'll have to post the link next week to their own LONG discussion as I don't have it on this computer.
The questions I can think of would be :
1) Does overhanging the front of the Deuce over the lunette frame cause any issues (if so use a trailer with a longer bed or swap a single axle in the rear of the trailer instead of tandems) - or pull the winch and the bumper I guess.
2) What is the real world effect on the the actual weight on the towing Deuce's front axle under this setup. My college physics statics & dynamics course says some of that trailer weight would actually end up on the front axles of the towing Deuce not just the rear axles/pintle hitch.
3) Is putting 8000 pounds on the pintle hitch one of those really bad ideas ? If so I guess this example would still work if you used a M275 Deuce tractor or a 5th wheel centered over the rear axles of the towing Deuce.
Other things to consider for adjusting purposes would be pulling one tire/wheel combo off of each of the recovery deuce tandems and putting them in the bed of the tow Deuce. This would transfer about 1000 pounds from the total weight on the trailer. Keep in mind too, that a Deuce w/ow would be about 13,050 pounds - TM does not say if that includes fuel or not - anyone know ?
Anyways - if this would work this option looks to me to be much safer than a lot the other non-CDL recovery options I have seen people do here. And you could make it even safer considering that there are now a LOT of cheap ($4000 to $8000) used non-CDL Internationals and Freightliners on Ebay and elsewhere right now. Or just skip the trailer altogether :

So what do the experts think ?
