Hi Joe, do not think you should have any problem regarding power.
Just check the total weight of the coach and toad. to stay with in capacities.
GVWR (Gross Vehicle Weight Rating):
The maximum permissible weight of the unit, including
the unloaded vehicle weight (UVW) plus all fluids, cargo,
optional equipment and accessories. For safety and
product performance, do not exceed the GVWR.
CW (Curb Weight): The weight of the unit without factory
or dealer installed options, plus allowance for the weight
of full fuel capacity. The “payload capacity” for all other
fluids, cargo, occupants, optional equipment, and
accessories can be determined by subtracting the CW
from the GVWR.
GCWR (Gross Combined Weight Rating): The maximum
total weight of the loaded unit, plus a tow vehicle. This
includes the weight of both the unit and tow vehicle,
fuel for each, all other fluids, cargo, occupants, optional
equipment and accessories.
Have a safe Trip and enjoy yourselves.
