What year Mega? Whe you say "on the way" do you mean brand new? I am nopt up on the new models. Is it a model with 17" rims? If so, tires and wheels could be your weakest link. Even if not 17's... I would look close at not only the "letter" rating of the tires but also the weight carrying capabilities of both wheels and tires.
When I had mine, there were limited choices of tires with a load index over stock (LI>121)
