I follow the guidelines of the chassis and generator recommended schedule which is a mileage or time event trigger, which ever happens first.
Keep in mind the guidelines are what the OEM has determined to be the minimum necessary to ensure the product operates thru the warranty period. There is always a minor risk anytime you do any maintenance (strip or cross thread a fastener, break a wire,,,) but generally the only problem with perform maintenance more often is the increased cost over time for consumables.
