Have you tried an Australian saddle? I really like mine. Also, you might consider a McClellan. Although the seat in a McClellan isn’t soft, It puts most riders in a very comfortable position and it has lots of attachment points for your stuff. Doug Kidd at Border States Leather Works makes new McClellans on a wider tree in case your horse is bigger or wider than the old-time cavalry horses.

Doug can make the McClellan in a variety of combinations according to your needs, including a padded seat as was used in the senior officers’ saddles. It sounds like some modification of the M1928 would suit your purpose.[/QUOTE]
There’s an entire world of military saddles for longer distance riding. They were the original “endurance” saddles.
That said, they were not all created equal. The Mac is loved by many and can be had in very good quality at very reasonable prices because there’s not much too it (I, personally, find it a “blister rig” but that’s must me ). The last version made in numbers was the 1904. It was the most sophisticated of them, having an adjustable girthing system. Many were later converted to the 1928 version with the addition of flaps and an English style girth.
I really like the predecesssor of the Mac, the Grimsley Dragoon saddle. Comfortable, deep seat and generally “fit” me. Here’s an example:

If you want either a Mac or Grimsley then Doug is the man to talk to.
Another commonly available type is the British Universal Pattern saddle. This is the oldest, continously used piece of military equipment in the world. The first model was in 1796; it’s still in use today by the ceremonial units in London.
It’s not a “close contact” saddle. The rider is “suspended” above the horse. The downside is a loss of “feel”; the upside is a reduction in stress on the horse’s back. It’s odd the first time you ride one; you get used to it pretty quickly.
Here’s the 1902 version: http://www.museumofthehorse.org/collections/introduction-to-the-equestrian-saddle-collection/army-saddle-united-kingdom-after-1902/
Here are many variations on that theme: https://www.google.com/search?q=tucker+trooper+saddle&rlz=2C2OPRB_enUS0537US0537&biw=960&bih=528&site=webhp&tbm=isch&imgil=9hRNRV5Aux5fDM%3A%3BY0YQw7EJoVRi2M%3Bhttp%253A%252F%252Ffhotd64476.yuku.com%252Ftopic%252F56608%252FSOLD-Tucker-Trooper-Saddle-500&source=iu&pf=m&fir=9hRNRV5Aux5fDM%3A%2CY0YQw7EJoVRi2M%2C_&usg=__igPE2zjp_f0OLVIQZnOQL41QVyU%3D&dpr=1.75
There are many others out there but these are commonly available in the U.S.
Good luck in your search.
