Any problem with upgrading to a higher amp battery? These trucks only have a 610, and I'd like to upgrade to a 850.

There is no need to go to a higher CCA battery. CCA is for cranking, nothing else. Reserve Capacity or Amp hours is what keeps your battery from going dead as fast when you play the radio or leave your lights on.
When you go higher in CCA in the same physical size battery, you have to add more, thinner plates. This gives you less surface area and there for produces less Reserve Capacity, or current over time. The system needs that Reserve Capacity to properly operate the computer controlled charging. Plus the thinner plates are more subject to vibration.
A 610 CCA battery is more robust internally than an 850 in the same BCI group.(battery size and configuration)
