Just my 2 cents.
I used a '95 3.0, 5 speed Ford ranger to pull my #2000 sailboat out of some steep ramps over the years.
If the ramp was steep, or look like it might be a hard yank, I'd use low range, just cuz it doesn't heat/beat my clutch. (never just used a parking brake with a manual trans. U Tube is FULL of guys who did! I leave it in first AND use a block on the front driver side wheel)!
Yeah, I didn't really need it, I coulda slipped my clutch to get going, but why?
Low range has the gearing AND the front wheels are pulling too.
My buddy uses a Subbie Outback to yank his 20' almn boat with a 90 HP Honda 4 smoke motor ALL the time (we think it goes for #2300 on trailer.
I'm going to use my CRV this summer to haul my #1800 fishing boat out.
the ramp isn't steep as ramps go, but a good 10-15 degrees.
