I plan on buying a 4000 peak watt generator. It will be me, the wife, and my 2 year old boy for now. I imagine we will only have 4 people in the truck at any given time. I want to be able to haul my 220 lbs xr250r in the bed of the pickup but I would understand if that would be too much. I would appreciate any advice.
