Go drive a Chevy/GMC with the 6.6. mtmuleyBumping this thread. I have 175k on my 2nd gen Tundra and am entertaining getting something newer and potentially a 3/4 ton. Might be pulling an 18 foot equipment trailer with a 6,000 lb piece of equipment on it for some volunteer projects, so towing 8-9k lbs a few trips year plus any hunting where I'm pulling my 6x10 enclosed aluminum trailer.
Things I've been considering:
Diesel - I don't think my needs require diesel, probably 25% of total miles at most will be towing. Diesel would be nicer sure, but generally the increased upfront cost, the more expensive fuel, the more expensive maintenance, and more potential problems all remove diesel options from the equation.
2500 Gasser -
To me the Ford 7.3 and the Ram 6.4 Hemi are the only options available. 7.3 is really enticing, but expensive, has it's own set of issues (tranny and lifter issues), it's a big truck that will just barely fit in my garage, and it sounds like it's a pretty rough riding truck, even with the tremor package.
The 6.4 hemi is a proven engine, the ZF 8 speed transmission is one of the best, it runs a little higher RPMs than the 7.3 when loaded, but rides better, is a bit of shorter wheel base, has better offroad packages available, and the hemi tick (which was a substantial lifter issue) has seemingly been remedied by Ram as those issues have dramatically reduced from several years ago. Both Ram and Ford have a pretty good power train warranty behind each of these trucks and performance by most metrics is pretty similar as well. So it comes down to price and better fitting my needs. Ram is getting the ever so slight edge for me here.
1500 - If I'm staying in a half ton, the gen 3 Tundra is the only option for me. It's one of the best 1500s suited for towing with the twin turbo and the way they have the 10 speed configured. I have some bias for toyota. Yeah they're spinning main bearings on about 1% of their production, but in my experience Toyota has always taken care of me if there's a problem. I've had really positive experiences working with Toyota and with my local Toyota dealership. Plus, I think they've got the problem identified and a new fix is supposedly being announced this spring. So, I would expect 2027's to be completely remedied (potentially). I would be comfortable buying a 2025+ Tundra and knowing if I blow a main bearing, I'll get a new engine with the fix. Still a PIA to deal with, so I'm still debating the 2500 options.
