Which would you buy. I am looking for a old / affordable truck. These are all used from private parties, around 3k asking price. I just need to load up the flatbed on most days but about 1/5 of the time I will be towing dual axle 10,000 lb loaded trailer. 86 npr manual 180k 14' flatbed, 11,300 gvwonly 115hp engine... But I must mention I don't mind cruising 55, going 30mph, or even 15mph up the grades if the truck can actually handle occasional use with trailer 89 dodge diesel 1 ton 727 auto trans, 220k+ 12' flatbed, 11,000 gvw 160hp? 93 7.3 ford f450 12' 5spd idi 95 7.3 powerstroke f350 4x4 auto, this one is a little more expensive and less gvw Biggest concern is mpg, and I don't think the fords will do well in this regard, especially the IDI (I had one before and averaged 10-12 unloaded). I prefer the 5 spd, and the dodge cummins is an early model with non-od auto trans, might get the best mpg, but I will have to go slow. The npr's supposedly get great mpg but my experience has been this is not necessarily the case if you load them down. I will be driving with a good load on the bed most of the time... input appreciated!
