Jplayer,
You made an earlier comment while OSHA does not clearly state how long Daily Inspection reports are to be retained, it is advisable to keep records in case a legal situation arises from an incident. At this time, I would think the best person to determine how long they should be retained would be the company's legal council. Most OEM's do provide a daily inspection report form for new equipment in some form as CYA practice. Kinda' like all trucks should have an operator's manual when delivered to an end user, new or used equipment. While having the manual on the truck may not help one in a legal battle, not having one on the unit can hurt you - this is one reason many manufacturers have the operators manual wired to the truck, typically in the seat back pouch. While most new trucks will have the manual - not so many used units do.
