No, but there is a weight limitation in the cargo area, especially in the base model. I ripped out the seat and the cargo area crap and covered the whole thing with 3/4 plywood. Nicely done of course with carpet and insulation, but effectively no weight limit. I did it more to carry a bicycle inside upright and still sleep in the car, but I could haul a lot of heavy stuff if I needed to.
