Need help please?

Hi Guys,
Long time lurker here.
Currently I'm in the market for a toy hauler and my requirements are:

Has to be a TT not a 5th wheel
Separate garage area
King bed
My tow vehicle is a 2013 F250 diesel and I want to stay safely within the bumper pull limits of the vehicle.
High quality construction inside and outside, wheel and axles.

I looked at many units online but I want real world reviews and suggestions if possible.
It's really confusing for me since this will be our first toy hauler.
Thanks

Northwood Manufacturing makes the Desert Fox TT toyhauler. Might look into it. I am not sure about the separate garage but it meets most of the rest of your requirements. They use their own frame, is four season insulated, and has a good reputation for overall quality.
