If thats all your are hauling IMO you have more motor than you need, I am a tad bit biased I love the 300 and would only replace it with a 4BT.

300=??? is a 4BT a 4 or 5 speed? is a swap to a 5 speed more involved than a set of pedals. also are there any 5 speed trannys that dont have the twin clutch/PP setup? which rear end ratios generally come in these trucks?

The ford 300 or 4.9 inline 6, 50 year production run.Ford quit making them available in trucks after 1996 cause they last too long! Cummins 4BT 3.9 turbo diesel inline 4 mostly used in older bread vans/ frito lay trucks

twin clutch/pp? you mean the dual mass flywheel? you can use a standard setup. just add shifter, pedals, trans, clutch hydrualics, may need a shorter rear drive shaft

If you want better FE get a manual trans a ZF5 would be perfect nice creeper 1st and a .70 overdrive. EOC is the the best way to improve FE manuals are much more eoc friendly.

22 mile trip last night 9.5 miles eoc. I would share the mpg I got on that trip, but no one would believe it.

ok, you have permission. what, is it, that you do that gets you 20 -30 mpg in a truck?
Pretend there is an rotten egg between my foot and the gas pedal, Engine Off Coasting which is usually 1/3 or more the total distance traveled, that trip was almost half! so basicly I was getting mid 20's while the engine was running and infinity while it was off driving the mpg up, speed limits on most routes I take are 25-45 mph, at 35 on a flat I'm at 1000 rpms in 5th gear.

42.14mpg but that was just 1 22mi trip.

We cant understand non-V8 engines because that ain't whut NASCAR uses...
