Look for a idle down feature nothing less than 5000 watt, most folks buy less than they need then rebuy the generator. Make sure if leaving in the van to have adaquate air flow doors open or unit will overheat. Overhead valves, preasure lube system and oil filter. Use synthetic oil the unit will start easier, run 18-20% cooler than standard oils and reduce overall maintenance, electric start is nice but also increases the wieght of the unit and additional cost and upkeep. Most manual start engines have a compresion release system on the cam which makes for easier starting by redusing the compression oce the unit starts the compression release retracts and the engine operates on full compression. I serviced and sold Generac units for years less expensive than Hondas yet are dependable, least dependable were Coleman.
