When I was looking for a new truck in 2015, the trucks with the features i wanted appeared more often with a 4.3. The trucks that had the 5.3 were either too plain or two dressed up for my taste and budget. The real cost difference for trucks on the lot was not $1,000. I either had to pay for unwanted trim or sacrifice other features to get a V8 for the price I was willing to pay. If the situation was such that I found two identical trucks except for the engine, with a $1000 difference in sticker price, I would have hesitated for a minute and picked the 4.3. I am also aware that dealers are/were more anxious to negotiate on their V6's. My experiences are such that I went through decades with trucks pumping out between 100 to 200 hp. My 81 and 85 Supercabs, for example, had longer wheel bases than my current 2015 cc std. bed. They pumped out approximately half of the horsepower yet they took my family on long road trips and pulled or carried many heavy loads. To me, a 285 hp engine was a no brainer! If I was in a position to be regularly hauling loads beyond the limits of the base engine, I would upgrade to the 2500/3500 series.
