Thanks for the input...much appreciated.
Couple of takeaways..
- "if it doesn't have a 16' bed, it's not a truck": We won't talk about the F550 Dump that I also have nor the KW Tractor nor the '47 GMC dump. :) I guess the KW doesn't really have any bed....but I just sold it, so a moot point. :S
- Truck will be a non-hauling driver a good part of the time, and it will have 4 doors. Since my comparator is that F550 Dump, I'm not worried about parking, but I do need to be able to turn around at the boat launch with a 30' trailer behind me....that might turn out to be the decision-maker on the bed size although with the modern wheel cut angle, I'm sure anything will turn sharper than the '09 that the new truck is replacing.
- "Get the tow package": Early indicators are that I can get a beefy 350 / 3500 in either standard bed or long bed. If for some reason, I can't find a stout standard bed, that will be the decider: I won't get a "underpowered" truck...minimal benefit compared to the "when you need it, you need it" issue.
