Nissan's financial future has been a mess for 25yrs, yet they sell a lot of vehicles. I don't see them, nor their dealer presence going away.
@dlundblad forgive me if I missed it in this thread, but is the need for a midsized truck that great? As much as I like my 2022 Frontier, I liked my Ram 1500 classics better. A ram 1500 classic with a pentastar V6, quad cab and 4x4 is an excellent truck in terms of fuel economy, ride and comfort. They turn tight, easy and don't feel big. They ride like a cushy full framed Buick. The pentastar certainly isn't perfect, but it's excellent in these trucks. The steering on the Frontiers is very heavy in comparison, with the old school hydraulic rack & pinion on the Frontier. Not a bad thing of course! Just tiring if you are behind the wheel for a long time. The turning radius on Frontiers is notoriously horrendous as well as I am sure you've read. It isn't too bad with king cabs and crew cab short beds, but if you should happen upon a Frontier crew cab, long bed, they have a laughably horrendous turning radius. My FIL has one (2017 model year), the 2022+ is unchanged in this regard. You wouldn't think that extra few inches of wheel base would make that big of a difference, but it sure does. It's really a non issue though as CC LWB frontiers are a pretty rare find.
I know you don't want a turbo. I never thought I would either. We have some basic Silverado quad cab, long bed, 4x4s with the 2.7T at work as plant trucks. I really enjoy driving them. The power is quite surprising.
