GMC vs Ford vs Chevrolet vans?

I'm currently trying to buy a Van for my construction business needs. There are three brands which come to my mind, GMC, Ford, and Chevrolet. Which do you think it's better, GMC, Ford, or Chevrolet, in Vans category?

GMC and Chevrolet are pretty much the same truck. Both made by General Motors. Ford has just introduced a new line of "Transit" vans, and Nissan also has commercial vans that would meet your need. I suggest you turn off your computer and actually go visit a few new car dealers to see the vehicles you are asking about.

I have a 2007 GMC conversion van. I like it greatly.

If you intend to carry heavy loads then the choice would be Ford. But then it all depends on what Ford you pick. Something with a solid front axle would carry more and last longer, you won't find that in a GM.

I think they are all the same, if going with used. Have it inspected. TRy to go with new or low mileage since you have no idea of how well the previous owners took care of it.
