You wouldnt have anything else than a turbo diesel in those conditions. And I have driven a few bt50's, very nicely setup turbo. But unfortunately we are talking wagons, and cruiser ones at that. A dayly commuter/towing a boat distances for holidays. Its funny how my mates with turbo diesels envy the V8 auto guys when using as a normal everyday car (city driving). And when they go away on holidays the V8 guys envy the turbo diesel guys... It a vicious circle...
But all the tests have been done many times over the years. Nomatter how much hp you have or dont have, makes no difference at all when your in low range. Fact
