I have a 1948 camper that weighs about 4000 lbs. I want to pull it with a 1948 Super 8. Can it do the job?

G'day chris p,
![]() However, putting that aside, I invite you to include your '48 Super 8 in the Packard Owner's Registry here on PackardInfo!

In my personal opinion I would not trust a 1948 Su8 to tow a 4000 lb. trailer. The Su8 may be able to get the whole rig rolling, but your biggest problems are getting it to stop and maintaining control while you are underway.
In the state of Michigan an independent braking system is required when gross weight exceeds 3,000 lbs. In Ohio their requirement is 2000 lbs. I spoke to my brother about this as he worked as a project engineer for one of the largest OEM suppliers of trailer hitches for the auto/pickup industry. He is unaware of any 6V electrically-operated braking systems you can add to the trailer or you Packard. And he does not trust the mechanical/inertia systems to keep your trailer behind your car in a stress situation. BTW, are you a member of Motor City Parkards? If not then you need to join. We have a GREAT garage tour coming up on February 15th to see some custom-bodied Packards, Duesenbergs and Cords. And we have former Stude/Packard engineer, Jack Smith, as our guest speaker.

How did Wally Byam do it?
If you want to badly enough you will find a way...safely... I hope it works for you; it is a neat idea. Of course you have to be nuts to think that way.... Be sure and take at all times an extra helping of prudence....

In my opinion it's a poor idea but you might want to look thru the frame strengthening and reinforcing recommendations that Packard suggested for trailer towing with their 55 models and see how that might translate to an earlier model. I believe it's TSB 55T-27.

One other thing to be thankful of/about: Ultramatic.
You don't have it! I'm really not going against OD; I just believe in dreams. That said, be sensible and careful about every aspect of this project.

Over the years I have towed a lot of car trailers carrying Packards with Packards. My 53 Clipper Deluxe with Ultramatic was an excellent tow vehicle with very positive braking for an Automatic box, particularly in Low range. But then the 327 does not put out enough torque to worry the Packard transmissions. I have not towed more that 2000 lbs with my twin Ultra 56 Patrician and that is because the TL suspension appears not to be able to handle more than around 500 lbs downward on the towball ( with say another 300 lbs in the trunk) without the TL bottoming out. I have towed car trailers with the 38-120 with the R6 overdrive and it is fine but R6 Overdrive is only for the flat country, not hilly country. although I have fitted uplift spring helpers to the spring pack and you definitely need to reweld the rear axle spring saddles onto the differential banjo as they are very lightly secured. I broke a set on my 38-120 a few months ago during a vigorous acceleration/ heavy loaded situation. A buddy brace is also needed on the rear chassis cross channel behind the fuel tank. Dont rely on the chassis dumb irons alone.
IMHO, it is a marginal exercise but if for the sake of authenticity, you are towing a 1948 caravan with a 1948 or thereabouts vehicle, and you are reasonably careful, then it would not stop me from doing it. You need to look at your local regulations of course to see if you can legally carry out this activity. Good Luck. PT

Peter, your observation is very consistent with what Packard said for the 1955's and towing. They recommended for vertical loads on the tow bar of over 500 lbs, that the frame side rails be reinforced, a load-leveling type hitch be used, and that supplemental lifts be installed. Just confirming, it's in STB 55T-27.

Back in the 70's we used the 55 Patrician to pull with chains our 66 Chrysler back to town. No tow bar, just pulling, with the Ultramatic.
When I got the Patrician, I always loved it when the torque converter would lockup, it was like the car dropped down, and wax ready to go!
