Definitely. I think a Tacoma would do that easily.

Sure, after a Tundra brake, engine and transmission swap.
Dunno, maybe the 3rd gens with automatics will do it. Mine would get that weight moving on flat ground but without a supercharger it's not going 60+ over passes with it.
I just did this, so it's fresh in mind. Lack of trailer brakes aside (that was the main issue, solvable of course), it wasn't gonna win any land speed records.

Just thought I would bump this with the news of AEVs partnership with Chevy. https://youtu.be/69vXouG9L8o

Aprosise: How many miles on the ZR2 at the time? There is a know issue with the diesel with low miles, the programing will not allow full power till about 5000 miles. the engine is not fully broken in till about 30-40k miles. that may of been the issue. Tow capacity on the ZR2 is 5000 lbs, bed capacity is 1000 I believe. There is also the wind pull on the trailer.U- haul Double axle trailer are quite heavy and do not have great aero. Some of that may come in to play as well. I do not think the ZR2 was the right Tool. Nice experiment thou.
So the AEV build ZR2 will be similar.
My Z71 on the other hand has a bed capacity of 1450 for the long bed, has 7500lb towing capacity(500 on tongue). There is these guys that do Towing tests up from Silverthrone and use a 5000 lb load in a double axle trailer, and yes the milage was about 8.6mpg according to the built in display. Where the new Tacoma with the 3.5 did beat the chevy with the same load by a few Seconds, the fuel ecomany was like 4.5MPG. and the engine was screaming(fun video to watch).
My expericene with the Z71 had been quite nice. I have about 55k miles on her now. Two trips to Alaska thru Canada. Last years round trip was 7500 miles Average 25.5mpg with a topper and full load, roof top tent. Speed average was 55-65, On Michelin tires(LTX M/S2 LT235/80 17R). This year was 11K miles, same set up(roof top tent on Topper, load in side), On Cooper AT3 tries(255/75 R17), average about 23.5MPG. We also did the Dempster up to Tuktoyaktuk and had a nice dip in the Arctic Ocean(kid and I). The road was mostly mud after we got off the plateau past Eagle plans road house. 1100 mile round trip,Quite an experience. Reminds me of Alaskan road in the 70's and the old Cassier HWY in Canada.
I do believe it would be hard pressed for the new Tacoma to do the same loads and get the same fuel economy.
I see on my typical drive up to the house in Sunshine about 18.5-19 mpg where the Wife's 07 Runner with same size tires, returns about 13.5MPG on the same drive. I am heavier by a few hundred lbs.
ON the open highway, the wife sees about 21, I see about 26 (still a topper, and yakima rack). I also have stuff in my bed(topper is about 300lbs, misc is about 150, Fridge, battery, 2X3 frame work with some ply wood for a sleeping platform.
I do currently have a 36gallon Titan replacement tank with is real nice(stock was 21).
My Z71 has hauled 1 cord loads of mixed hard wood and full cords of Oak up to the house via Sunshine Canyon road(oak with trailer about 5000lbs). There are a couple of 6-7%grades that if I wanted I can fully accelerate up the road with the load. I typically do this with the Mutli mode T-case in all wheel drive mode(even thou chevy does not call it that, it act like an all wheel drive. Splitting torque more forward to front wheels). If I recall right, the Tacoma does not have a Multimode T-case like the 4Runner.
While these are not a modern full size truck, I would compare the Chevy Mid sized truck to the old heavy half tons. They do the work of a heavy Half ton.
I can do a pro and con of the Chevy at a latter date. My biggest pet peeve is the Wheels.
chevy did not use the old 6 lug pattern that is similar to the Toyota. this new pattern does not allow a bunch of options for wheels, Maybe in a latter date( I really want the option to run the 235 or 255 width tires better, no options currently for 7" wide rims except on a 16" steel rim).

Reports of the side curtain air bags going off while offroading are starting to pop off. Apparently Chevy is saying the system is working as designed (going off when a roll over is detected) even though none of these recent cases getting publicity involve a roll over.

Seems like a fine line for a manufacturer to have to walk. If they're selling roll over curtain airbags they'll need to work pretty fast to do any good. It's an strictly an angle, rate of change, what exactly should be the criteria for them to work?
A slow crawl where you flop over is still a roll over but you wouldn't want it to necessary fire but by the time you've gone a whole revolution it might be too late. But then is a few degrees at some velocity the trigger? We've all been on sections where we get bounced left-right pretty hard so it could easily be mistaken as the start of a roll.
The solution to turning them off with 4WD or low range isn't sound, rolling in snow or on a shelf road might still be nice to have those curtain airbags trip, since you got 'em might as well use 'em.
Toyota used to put a RSCA button in the Tacoma that you could disable the curtain airbags if you wanted but I think they removed it in the 3rd gen. Probably a liability potential even if the owner turns them off, so in a litigious society the lowest common denominator wins. Even if it's not that the engineer(s) who worked on the roll curtain may have just been too aggressive in their algorithm and erred on the "safe" side so to speak, maybe not fully accounting for off highway in their testing for pavement rolls.
Guess it's something GM got wrong potentially but they've all had times when they made mistakes (unintended acceleration?) with software or could in the future (Toyota and GM use the same Takata airbags, maybe a subcontractor issue?).

I’m going off of memory, but I believe the rsca button does not completely disable rsca’s it just drastically changes the thresholds like from 42 deg to 66deg (just and example).
Land Cruisers still have the RSCA button still, as do the GX models.. so doubtful that was discontinued. though I question its usefulness, I always forget to press it. Then I drive down stuff like Wipeout Hill, etc. Next light switch I add that will be the next button to go behind the panel, right next to the dashboard rheostat.
