Where you're planning to put those batteries will directly affect the weight placed on the cantilevered front. It isn't a matter of how much weight the truck can carry, it's how the trailer "base rails" transfers weight to the pinbox. The "weak link" in many fifth wheels is how the front "superstructure" converts horizontal to vertical loading.

This is fantastic knowledge! We're checking in with Keystone now about permissible weight for the passthrough. Wonder if it would be possible to retrofit the front section?
