3.73 and 245 70 19.5 tires. 6th gear has been open for business for quite awhile now. How do I figure out if the driveshaft can take the rpm besides the obvious grenading.

What tongue and hitch do you have on that?
You have a lot of tongue weight. I have snapped a hitch receiver and broke a hitch with too much tongue weight. It only takes a rough road and it will let go. My receiver and draw bar on my F550 were rebuilt using 1/2 wall pipe and a solid steel draw bar bolted to a 20K receiver. I still would not want a skid steer sitting on it.
If a trailer has a 6" C channel frame - the channels will bend behind the rear wheel and they will bow out in the front half of the trailer. Check and see how far the clearance is from the u bolts to the frame when loaded. They can touch and rub.
Yours might be 8"s cant really tell.

Truck has a proper 3/4" thick pintle plate welded to the frame, and gusseted. Truck frame shear strength would be the limiting factor long before the hitch gives out. 60k pintle on the truck. Wish the truck actually had a 2" receiver so I could move lighter trailers...Another project for another day.
Trailer is 8" C channel with a 50k lunette ring, double framed at the front. My skid is smaller than it looks - 7400lbs with bucket and full fuel. Full weight of the machine isn't on the tongue, at most there's 4k of tongue weight. Quite a well designed trailer actually, only gripe is the fenders are kinda thin, and the ramps have no spring assist...and they're about 150lbs...next trailer will be a touch longer too. But this was a good deal, so I can live with it for now.

I like the concept of a two speed rear end, but it gets scary when they get stuck between hi-lo. That probably doesn't happen very much anymore, but it certainly has the potential to.

When you have an automatic you don't usually shift the 2 speed on the fly like you do with a stick.

My suggestion was for Underdrive when go Off pavement, not so much shifting on pavement.

Very nice. I could use a trailer like that. If you get tired of it and you happen to be in Georgia bring it on by! I have been thinking of going to a 22' deck for me to be able to carry another 5' of gear. I bought this trailer but it is heavy...

My wife's cousin has a pair of International dumps (single axle, ex-municipal, early 90's) that have Allison's and 2 speed rears. They automatically shift to high once truck is at speed in 5th gear. They are electronically controlled, don't know much about them beyond that.

Interesting. The last time I saw one on an automatic was a Ford or IH (can't remember) cabover medium duty from the 1980s. They had specific instructions on shifting but I don't remember what they were now.
I can see the problem shifting rear end speed in a gear other than top gear because the transmission may respond to the throttle input by shifting itself and making synchronization of the rear go all out of whack, or impossible.
