I agree. A 4BT rattles and shakes and makes a lot of noise. It is much
heavier than the gas engine the trucks came with. A 6 bt is bigger and
heavier, and the new ones are more refined, but it is too heavy for half
or 3/4 ton peekups. A 6 BT might work in a 1 ton, but for 1.5 or 2 ton,
its da bomb.
An OM 603 at 125 HP is at least as good as a ford 240 or 300. Yes, it
cruises at 3000 RPM, but that should push along the truck with the
original rear end at highway speeds. If you turn up the fuel some and
add a couple PSI of boost it should equal the HP of a 300 cubic inch or
so merkun gasser. It will be no more weight, perhaps lighter than a
small block frod, shovey of dogde.
I am not thinking of any newish truck. a 1980 or so frod would be the
newest I'd look at. 1966 to 1968 (GM, frod or dogde) or so would be
preferable.

I've never been so excited about driving big truck engines in
passenger type vehicles. The only 6BT I drove was an '01 24 valve and
it had nothing on an MB or VW diesel.
Gearing decides where you rev to. For a 1 ton truck the 6BT is
probably the best choice but for something smaller like a 1/2 ton
truck doing light work a 602/603/606 is probably fine.

They don't have much torque until they rev. A 4bt is much easier and
cheaper to fit and tune in any sort of truck here in the us.
