I've sorta been looking into them as a next daily ( yeah yeah, I know ) but I was seeing if anyone knew of any problems that tend to frequent them ( outside of being made out of plastic lol )

Essentially my next DD is either a wagon ( Dodge Mangum, WRX wagon, Legacy?, Mazda Protege 5 ) or a truck ( like a Tacoma Double Cab ) - problem is, I want to be able to haul stuff around, be able to go off road ( no off road, just off the road like dirt or gravel roads without much issue ) and still get decent gas mileage ( which the Tacoma kinda doesnt )
