HI Moras,
Good point on the consumer side. Every time I buy something for the kids that requires assembly, it seems like there are instructions in no fewer than 5 different languages :-)
I was looking at my post again and I didn't think I really covered anything on service or customer follow up unless maybe you're referring to the modifications to the trucks. Just in case I have caused some confusion there, the big names in heavy equipment add these packages during the assembly process. They have a build order and if there is one of these packages on that build order, they pull a kit from inventory and make the additions while they are assembling the equipment. If you have a good assembly process, adding one of these kits should be a standard routine. That being said, without knowing who this manufacturer is, it's hard to say if they have such a process.
As far as service and follow up, I don't know of any instances in the heavy equipment industry where you would go directly to the manufacturer for support. You typically work through the dealership. I believe in this case, AmeraMex is acting as the dealer. I may be off as my memory is not that great, but I think it was mentioned that Ameramex was providing training on operation and maintenance of the equipment as part of the deal. Someone with a better memory, feel free to correct me on that.
As far as soliciting bids, I would have to say once again, this would not typically involve manufacturers directly. The bids would originate from the sales department of the dealership. Once again, I believe that AmeraMex is filling that role. I'm actually hoping that they will be providing parts for maintenance and repairs as well.
This is all IMHO as always :-)
