Heavy hauling

[pinzinator]

About a year and a half ago I rented a dump trailer and a mini backhoe to move some dirt out of my back yard. I hauled 19 loads over the course of the weekend, and then hauled the backhoe back to the rental shop in the trailer. I never had a problem, but had to plan my stops well ahead of time. Most of the time I never went faster than 40 MPH or so.

Wow, that's the heaviest load I've seen with a Pinz. A 710 no less.

I had to be really careful with the tongue weight and not be in a hurry. Most of the time I had the transfer case in low range.

very surprised that they would rent to a customer with a vehicle as light as a pinz for a load like that. Good for you.

As if they would have any clue as to what a Pinz is/was let alone the weight!

Only mention it because a concrete co in San Diego would not let me rent one of their customer load trailers to pull behind my Tundra that was rated at approx. 9000lb haul capacity.
Truly most do not know what a pinz is, let alone what it can do.

So true TechMOGogy, makes me want to call U-Haul and try to rent a dolly listing the Pinz as the tow vehicle. LOL.

Not sure how it is in the US but here in Canada, Uhaul will not rent any sort of trailer if your vehicle has soft top
So if you own a J**P the will not rent you any sort of trailer - open or enclosed. Not sure why
Not sure if they would rent one to me for a Pinz?

You need to be careful when hauling a load that heavy, not because the
Pinz can or can't pull it, but because there are serious and uncontrollable
reactions when the load gets off balance or when you slow down.

A number of years ago I was the first person on-scene with a knucklehead
who tried to tow an empty lowboy trailer (the kind you use for a caterpillar
with backhoe) with a very small, lightweight truck. He was on a small rural
highway, probably going over 40 and either the weight shifted on a bump, or
he tried to slow down and the trailer jackknifed causing the two to roll, side
by side. The action whipped the truck, and the guy flew right out the window
and landed about 50 yards down the road. There was grey matter on the road.
needless to say, even with the helicopter getting there in a few minutes, he
didn't make it. He died about 20 minutes after I got there.

If you are hauling a load that heavy, put a bunch of weight in the back of the
Pinz to hold it down to the ground when you are stopping, or if you roll over
a bump in the road. be very, very careful. Glad you had no issues when you
hauled the dirt too.

I posted some of this in the other thread about hauling a haffy with a pinz - but its more applicable here:

Some of the difference in tow ratings could be maximum speed and fear of lawsuits these days...

In Europe, the max speed while towing in many countries is 90 km/h while in the US it can be as high as 75 mph. Obviously, the pinz would probably have been rated for a maximum of 90 km/h while the jeep would have to be rated for the higher speed.

I think the Jeep is being conservative - especially when you compare it to other models in the same jeep line-up such as the grand cherokee. Also, I don't think the longer wheelbase 4 door Jeep JKU models have a higher towing rate even though they have a longer wheelbase and weigh more... I think that u-haul is being careful as the previous models of Jeeps (the TJ and CJ models) had even lower tow ratings and shorter wheelbases - making them very poor choices for towing trailers.

My "first year offered" 2002 freightliner sprinter van (2500) has a max tow rating of 10,000 lbs - but the 2003 and later models (identical) which was then offered by both freightliner and dodge had it reduced to 5000 lbs - the story I heard was the the Mercedes engineers found out about people towing at 80 mph and feared lawsuits...

At the risk of getting off topic....

Actually Half-E yes, in regards to Wrangler's the tow rating could be anywhere between 1,000 lbs (2 door w/3.21 gears) and 3,500 (4 door w/4.11's). I think you hit the nail on the head in regards to speed. Overseas the speeds are lower so it isn't as big an issue.

I’ll go out on a limb a little and guess the low-boy trailer mentioned was equipped for air brakes that the light truck had no provision for, so heavy trailer pushing light truck when stopping = bad news. Being as most rental trailers (of weight) that I've seen have a hydraulic brake system incorporated into the hitch the trailer would primarily be being stopped by its own brakes providing a greater degree of safety.

I know I really feel the difference when I don’t hook up the electric brake connector when I’m moving my car hauler around in the yard.

Regarding the Jeeps capacities I would also suspect the frame construction is also a factor as they were never intended to carry much of a load.

I’ll add myself to the ranks of people that are surprised that they rented it to you, I remember having to prove to U-Haul that my 710K would fit on their car hauler before they would rent one to me for use behind their truck.
