I use my gmc 150 3/4t (same as 3600) as a daily/weekend cruiser. The long bed is great and it will carry a healthy load of firewood or wood pellets no problem. I swapped in a 4:11 center section and I run a borg warner electric overdrive. Im not sure I’ve seen them cheaper in my area because normally they are rare because they were beat to death with commercial use while the 1/2 tons were dailys or light use trucks. I do like the idea of the full floater axle and the heavy duty 8 lug wheels and bigger brakes. I honestly find the long bed very useful. The only downside to some 3/4t stuff is parts availability is not as easy as 1/2t and some parts are even NLA and ones that are available seem to cost more $$$. That being said.....I dont mind the challenge and I love my 3/4t to death.
