Welcome to the forum! The lift systems in Hilo trailers are quite reliable if properly maintained. The lift system consists of a hydraulic pump, hydraulic cylinder, cables, and pulleys. If they are checked regularly, cleaned, and lubed at least once a year the system should be good for many years. There is a steel rod, the guide rod, that parallels the cylinder that needs to be cleaned and greased also.
Most systems and appliances, outside of the lift system, on HiLo trailers are generic to most other travel trailers, so servicing is usually not an issue. Even the lift system is not that much different from those on popup campers.
One of the forum members, NDgent, made up a checklist to follow when shopping for a trailer but I can't seem to find it at the moment. Maybe someone will add it here.
