I imagine the reason we don't see as many Ranger builds as Tacoma and GM mid-size trucks is two-fold: 1. the current Ranger has only been on the market for 3 model years, so the others have a sizeable head start, & 2. when you go down to the Ford dealer to look at a Ranger, the salesman can show you an equally good looking and equipped F150 STX or XLT 300A with the 2.7TT that they can sell for virtually the same price (until recent market forces upended the massive discounts on full-size trucks).
Or less once you notice a crew cab midsize has a rear seat more on par with a super cab fullsize than a crew cab fullsize.
I sure wish they offered a Ranger with a larger tank.
Imagine, a Ranger with range.
I have been tempted by the dual tank goodness with mine. When was shopping for a better bed I was hoping I would happen across a double tanker... but I didn't.
But really my single does me fine even with a slobbering V8. I suspect many midsizers are similar with similar sized fuel tanks too. I can't see the fuel bunkerage being an issue with the Ranger when all of the rest of the midsize trucks (and Jeeps) are carrying about the same as well.
Personally my qualm with midsize trucks in general is the size. The cabs are not really super for a sasquatch to sit up front with a kid seat in the back. And then the beds are dinky.
If I have to use my '85 to haul everything I might as well skip a new Ranger and get another Bronco because a 5' bed Ranger will not run with my '85 packing 7' of cargo bay.
Otherwise I really wanted a '19 when they came out. I like the looks, I like the powertrain (even moreso now with a 2.3 Bronco in the driveway) and I was even ready to overlook the dinky bed.
Then after marveling how similar the interior was in size to my wife's Edge we put a car seat in the Edge... ok, that pretty much sucked. Knowing what to look for and paying more attention to that I climbed back in a newer Ranger and I think the Edge might have had a little more room.
And then I got a slide in camper. 5' bed need not apply. My '85 hauls it great but it is a two seater in a three butt family so longer trips are not ideal.
If I would snag a fullsize with a 6.5 bed, eezy peezy. My old F-150 toys with it but is a Super Cab and is pretty snug and my wife complains about having to ride in the back seat with the dogs a lot.
IMO the biggest problem with the Ranger is about 20 years ago Ford decided to give up on the truck and people went off to look for greener pastures. It will take time to win them back. Ranger was originally supposed to die around 2006 but the stupid things kept selling decent and the tooling was paid for so they let the line run until 2011. IIRC it was also around 2006 they lost the "best selling compact truck" claim that they had since 1987. It was Ford's game to lose and they simply threw it away.
I remember their idiotic mantra well. If you want a light truck buy a V6 F-150. If you want something good on gas get a Fiesta. There is no need for a compact truck anymore.
And now we FINALLY get the T6 Ranger (that globally hit the market the same year the old NA truck died) and the the smaller Maverick to boot.
And at least in the short term competing with the Bronco for slots on the assembly won't help their population on the trail either.
