I'm considering purchasing either the 2WD or 4WD FEH prior to a cross-country move (NY - CA) and to pull an additional cargo trailer. Additionally, I'm thinking I may purchase the cargo trailer for part-time work purposes. I'm guesstimating that I'd like to purchase a used, V-shaped, 5' x 8' trailer that would be able to accommodate the maximum 3,500 lb. towing capacity. Is there a significant benefit to purchasing the 4WD to pull an additional cargo trailer of this size, assuming that I'll be using it for work (primarily in an urban or suburban setting) on a fairly regular basis?
