Garage Size

The TrailerManor is everything my wife & I have been looking for. MOST important it has to fit in my garage.
My Garage measurements are as follows;
Door is 81 inches high & 7 feet by 10 wide
It is 19 feet & 10 '' from the back wall.
We would love to get the 2720SL but may have to get the 2619.
How is the hitch & back bumper counted in the depth?
Will the 2719 fit.
Thanks for anyway advise! ;D
