Are there any major differences between the Triumph-LS Rover + Triumph-2 Base rig and the Ultimate RTK package?
Would one be better than the other for mounting the base on top of the survey chariot ?

The Triumph 3 is out now.
It's a multi-constellation base, with internal 1 watt transmitter.
It can be run with Bluetooth connection to an external radio. Or, with internal.
It basicly is a direct replacement for the triumph 2, with multiple constellations, and added features.
Preliminary reports are impressive.
They won't send me one. Unless I send them money.
It seems that I don't have one.

As Nate suggests, with the release of the new Triumph-3, I would say that the Triumph-3 is the ultimate base station for the Triumph-LS RTK rover. The Triumph-2 is great. Nate and I both use it every day for the base for our Triumph-LS rovers. Mine has been very reliable, but it only tracks GPS and Glonass (no Galileo or Beidou). The Triumph-1M and Triumph-3 are capable of tracking GPS, Glonass, Galileo and Beidou, when proper options are activated. The Triumph-LS rover also tracks GPS, Glonass, Galileo and Beidou. In order to use a constellation in the solution the base must be able to track the constellation and send corrections for that constellation to the rover, which must also track the constellation and use the signal in the RTK engine.?ÿ

Javad now has multi-constellation solutions in the "pre-release" version and I anticipate it will be in the release version in a couple of days, once the development team returns from their holiday.?ÿ

If I were putting together the ultimate RTK package it would be the Triumph-LS and the Triumph-3 with all constellations enabled. Then depending on your communication needs, I'd look at possibly adding an external radio and/or activating the cellular modems in the LS and T-3 for sending corrections through TCP.

The John Evers report is:
A new saying: Javad did not just raise the bar. The bar is gone.
I was in Shawn's class a couple months ago and we had the very first T3 available in the US as a base for the class.?ÿ It performed admirably.?ÿ My business motto is to use the best equipment available for the job and charge clients for it.?ÿ There are no other choices for a rover but the LS.?ÿ My base is the IM with all constellations turned on.?ÿ The old phrase, a chain is only strong as its weakest link is appropriate here.?ÿ If you use a base that only gets GPS and Glonass, your LS with all of the other constellations available is not getting corrections for those other constellations and cannot use them unless you are using a VRS system with just the rover.?ÿ I updated to the pre-release yesterday with some fancy new colors on the buttons and everything seemed to be faster.?ÿ I bought my system March of last year and since then have definitely drunk the Kool Aid.?ÿ It has revolutionized my life, getting good shots in places GNSS has not been appropriate until very recently.?ÿ Chopping line is mostly out of my life.?ÿ I survey mostly smaller localized jobs less than 100 acres and with the 1 watt internal radio, I regularly get 4,000' of coverage and have gone 6,300' from ridgetop to ridgetop.?ÿ I am a big fan of the collapsible monopole for serious brush work and absolutely despise a fixed 2 meter rod.?ÿ I do not own a T3 yet only because they are just starting production of them.?ÿ It will be in the stable soon.

The best would be T3 on base.
Your choice of base to rover com's.
And the LS as rover.
Now, to mount the base on a truck.... I don't think any are better than another.
What I think you are talking about is:
(Here is my story)
I did a job, near a lake. All residential. All covered in trees. All over. I picked a house on a hill, and knocked on the door. I got permission. I set my base on a 24' pole. Bungied to the side of a 2 story shop. I then put my base radio on a rod, and ran it up about the same. Base was solid, would not blow in breeze.
I got it all going. And walked to the clearest place in miles. It was about 400' from the base. I set a nail. Observed it 2x. Then averaged it.
Then, drove a mile down the road. Did my survey. (As a side note, my 35 watt radio broke on this job, and fell back to 1 watt, but it was sufficient for all shots, except one, which got post processed)
Then, I went home, and processed it. This put it all on SPC.
If I ever have to return to this job, I can put my base any place convenient. Get autonomous position. Go hit that previous nail, that was about 400' from the base. Then, shift all so that this second observation on the nail, matches the previous one. It is now running on the same system, less about 0.02' or so. I will be able to find the nail, from the autonomous shot, within a few feet. Then, confirm it with cors to base processing.
This allows you to put your base up, in random locations, or on your truck, etc.
This works this way, with your own base.
I don't have experience with rtn's.
There is a bug in it right now, that won't allow you to select rtk, vs post processed (base to rover), but, maybe they fix it. The system works. That's the only drawback.?ÿ
Maybe this helps.

On re-reading your post and catching the part about mounting the base on top of a survey chariot, I will tell you what I know.?ÿ The 1M is fairly large, say 7" square at a guess and it sits on a 8" tall rigid post that is the antenna.?ÿ The machining is all quite good and everything is secure but it sits up a bit higher from the mounting point and is bigger and heavier.?ÿ The new T3 gets all the same signals but with faster processing hardware.?ÿ The body of the T3 is dimensionally similar to the LS except shorter and lighter with a small detachable rubber like antenna on the side, much like the LS has.?ÿ In a nutshell, it is smaller, lighter, and faster.
?ÿ ?ÿ There is a routine that I have not used yet called Reverse Shift.?ÿ Once you have a point established, instead of reoccupying that point like a 20' rod on the side of a house, if you have a good location to set the base you can set it up and shoot the known point with the rover and Alla Kazam! the base knows where it is and you carry on with your day.
Reverse shift, (has changed now, to be M-local. It stands for multiple local, when reverse shift was expanded, to allow shooting multiple known points, to check things. (Like if a control point got moved etc)
Here is a video:

Reverse Shift sounds awesome. Exactly what I'd be doing with a base mounted on the chariot. For now I'm thinking to order a Network Rover and bootstrap from there. Here is my question of the moment: With a Triumph LS network rover (sounds so formal!) and the WSRN, I'd be getting (I think) two constellations, GPS and GLONASS, and a VRS (usually) parked close by. Can the network rover cook that down to a repeatable tenth under canopy, even if it takes longer than with a local Javad base?
?ÿ
Well, @half bubble, since the t3 is out, there should be some left over t-2's available, at some less than new costs.
I paid 5k for mine, new.
I don't have a network here. So, that's out.
But, I suspect you will prefer a local base, for the performance gain.
I don't know that.
