The one thing that stood out to me was the demand to put a/c in the package cars, new ones going forward is easy to do but to retrofit the existing fleet is not going to be an easy task.
Kits are going to have to be developed for the retrofits for several body and engine combos, all modern engines have ECU controlled A/C so it's going to require atleast reflashing the ECU and body control modules. The kits are going to have to have wiring overlays since our trucks shipped without factory a/c and does not have the wiring in place. May end up needing modules too if the current ones lack the drivers inside of them.
Then who is going to install it, if it gets outsourced that is going to be a big national level grieve since that is our work, however there is no way in hell already overworked UPS shops can handle 100k retrofits.
After all that I think you guys will be disappointed in the results, these things leak air like crazy and no way will it cool the back in an uninsulated box
