weekend hauling with a 2500?

I'm thinking the truck has a 8800 GVW and something like a 10k GCVW if I remember right. The camper package doesn't do much for you while the air bags will help with the stability of the truck seeing it is not a DRW, they don't raise the GVW or GCVW.

 

There's a large overhead to running a truck... insurance, taxes, depreciation... regulations.

Would you rent a high traffic building, to have a store that's open just 2 days a week, on the weekends?

Only if whatever you were doing was in massive demand with a huge markup. And you'd be vulnerable to those who pay the rent but are open the whole week.

So, unless you have some kind of very, very profitable work with no chance of competition from someone else... This just seems like a lose-lose proposition.
