Another potential cause can be a radiator hose collapsing and restricting the flow of coolant.
Do you know the history of any cooling maintenance?
BTW Some of the cooling system changes you described like increasing the hydraulic fan speed sound like someone is trying to mask the problem because they don't know what else to do.
Monaco tested their rigs in the Los Vegas area. They towed a dolly and could simulate any grade in the heat for any distance on flat roads. They had multiple instrumentation to measure the engine. My 2 Monacos never exceeded 204F on grade in 115F air with cab AC running. Just some information.
