The gap behind the seat in the new gen rangers is a lot slimmer. I don’t think u will fit all that behind there. When I upgraded I had to sell my sub that went behind the seat and get one of those fibreglass boxes that go under the back seat in the tool box space
Not sure what country you guys are in but in NewZealand the sport comes with the bigger 3 litre v6 engine and 4wd. There’s a couple other little things like proper tow hooks and the exhaust ends just after the diff instead of sticking out the back
