I have a Motorized toyhauler and can say with authority that there is nothing better for you and your toys and pets (empty garage is perfect for the pups).
We searched and searched all the motorized toyhaulers we could find before buying, so will offer some of what I found.
Super C's dont seem to have the drop rear frame sections that are offered in the Class A toyhaulers (means steeper ramps or lifts), but none of the Class A's offered the power in the MDT's and HDT's.
Finally there is a BIG difference in price point...expect to pay much more for the Super C that has the same equipment inside the house part of the rig.
There are only a few companies in the motorized toyhauler business. The best known Super C's are Renegade, Toterhome, Conquest and the Seneca by Jayco.
And many Super C's require a non-Commercial class A or B drivers license because of the high GVWR.
If you decide - like me - that the Class A was preferred, check out this thread:
Best of luck
