Greetings. I bought a new 4Runner in 2018, and I mostly love it. Had a Pathfinder for 16 years, but it was time for something new as it has 287K miles on the meter (still running OK). I have 25K miles on the 4Runner, and I've towed my camper trailer behind it numerous times to the Sierras, northern CA, and central OR. My main complaint about the 4Runner is that it just lacks power. It's seriously underpowered in my opinion. Towing a 2,400 lbs trailer at 8,000 ft elevation on a steep incline is no fun at all. I'm basically revving the engine at 4,000 RPM and still only doing 50mph at best. In those moments, I just want a Ram 3500 with a huge ass, way overpowered diesel V8 with insane torque. Since I'm almost always towing the trailer for my trips, I've been toying with the idea of trading the 4Runner in and getting a vehicle with a V8 and a lot more torque/horsepower. The Tundra looks like a good candidate, or maybe even the Sequoia. I don't do any serious off-roading or rock crawling, but I would like to eventually build out the vehicle to be able to tackle some semi gnarly trails. I usually don't pick a trail because it's challenging, but rather because it might take me to beautiful places where most of the crowds can't go. That said, I do like good ground clearance, solid 4wd features, and most of all, a sturdy as hell vehicle that won't break when I do take it on some rough trails.

So now to my questions. It's not clear to me if the newer Tundras (2019/2020) have as nice 4wd features as the 4Runner (crawl control, locking rear diff, 4wd low gearing, etc). Another consideration is that the wheel base is quite a bit longer on the Tundra. Again, I'm not doing stuff like the Rubicon, or Hell's Revenge, but I do want a vehicle that could possibly tackle some tough trails if needed. I'm also thinking about after market parts availability. I do want a nice bull bar with a heavy duty winch, etc. I assume that there's a lot more of that available for the 4Runner than the Tundra. Or maybe I'm wrong? Any other considerations? I just wish the 5th Gen 4Runner had a reasonably lightweight 350+ HP V8 as an engine option or that I could afford a Landcruiser...
