Factory Installed Generator & Winegard Satellite

[jwjrta24]

I am looking to purchase a new Cedar Creek model 36B4,there are some options I would like to order or have installed later on.I am finding it hard to find any inventory out there with a generator.It looks like I will have to special order my unit.Does anyone know where the factory installs the generator on the 36B4 or has anybody seen one.My second question is has anyone installed the winegard automatic travler dish on their roof,just wondering if the roof can support this weight.Thanks for any help on this matter.
