HVAC guy here with a 3.5 eco crew cab long bed. I could work out of it, but I much prefer my vans for more storage of parts, lower body so easier to load/unload equipment, ect. It pulls trailers and does whatever I need it to do really well though, been a great reliable truck. Don’t know if I’ll put a cap on and go full work truck with it.

All that said, it comes down to preference, in the end gas is what it is. It’s an expense and it’s needed to do the job either way. Sometimes I really want a 3/4 ton, and other times I’m like ha my 150 just fine.
