"Joined at the Hip" ??? Hmmm. I thought that tandum towing was a lot easier than parallel towing.

Fred, Nice Fairlaine and receiver.

After having a U Haul "2" installed on our Nissan Van I was not impressed. The van came with 6 factory threaded inserts but the U-Haul receiver design only used 4 of them.

Within a few hours I fabricated some extra parts and welded them in place. The receiver now used all 6 threaded inserts plus a welded portion I put in place myself. So much stronger and flex free as I was using a WDH.

I'm waiting for someone to say that since you modified a factory design that your insurance will be cancelled, you will be sued and that your hair will fall out.

Good for you for recognizing and addressing what I think to be a huge problem with aftermarket hitches: disregard of factory mounting points for hitches supposedly designed by the seller to "fit" the rig it goes on.

Differences can be much more radical than those on your van.

We discussed one such situation recently on a Subaru (I forget which model). In that case the factory designed hitch attached at sixteen points, and included some reinforcing bars to be inserted into the frame tubes. The (cheaper) aftermarket substitute "designed" for the same car attached at only four points, two of which were to the sheet metal underside of the vehicle. No frame tube interior reinforcement.

And yet:
The owner is confident that performance/towing capacity is the same for both setups, an assumption I think dangerous. It would be interesting to ask Subaru whether tow capacity should be derated for the four-point aftermarket arrangement.

In my opinion, these very radical differences should be pointed out at least by the hitchmaker if not warned about in vehicle owners' manuals. It's likely that tow capacities expressed by vehicle manufacturers presume the use of a properly designed and installed hitch system.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

It's fine. I put one on my subaru and would do it again. It's not exactly "sheet metal" that it mounts in, and the front and rear cradles also mount to the same "sheet metal". I haven't seen a subaru on the side of the road missing one end or the other yet. They also do have a reinforcing plate that goes in there. That hitch will far outlast any weight that car should pull. Hell I've installed class 3/4 receivers in pickups that use 4 bolts and the frame rails aren't any thicker. You know what happened when somebody cut me off and came to a dead stop crosswise in the road, and I hit them at 45 mph? The pickup frame bent. Hitch didnt move.

One very IMPORTANT part of information in regards to that discussion that seems to have been missed is that Subaru only started offering up there own hitches a few years ago. For the first year they only offered a Class I hitch but many of their vehicles were rated to tow with a higher rating than the Class I hitch, so aftermarket hitches were the only option. Subaru themselves would just send the car owner off to the local hitch dealer to have an aftermarket hitch installed using the hitch attachment points they had designed into the car at the factory. So 90% of those towing with a Subaru here didnt have the option of using a Subaru hitch with the newer designed hitch attachment points.


Not sure as I haven't crawled under one to look but it may be that they still do build the new cars with the aftermarket hitch attachment points even though they offer their own hitches now. The aftermarket hitch I had installed on my current Subaru was attached using the hitch attachment points that Subaru had put on the car at the factory - no additional drilling required and they do go through more than sheet metal.

The hitch attachment points offered on the newer Subaru's to be used with Subaru's own hitches appears to be a better system. But it is very doubtful Subaru would have provided the attachment points for aftermarket hitches & supported their use in their manuals all those years, if they were not safe to use.

Dunno about your hitch/vehicle but:

The hitch we were talking about is an aftermarket one that Raz put on his Subaru- I think it was a Forester- and he specifically said that it attached at four points only, and that there was no interior reinforcement provided by the supplier. He himself expressed some trepidations about the arrangement.

I'd be happy to dig the convo up, but it seems sorta pointless since evidently the only evidence that counts is the "fact" that you "haven't seen a subaru on the side of the road missing one end or the other yet." (sic)
