I currently own a Quicksilver 8.0, love it for the leaving space for a familly of 4. Only draw back is when it rains, need to wait before mounting or unmounting the tent. Currently looking to put bigger wheels and tires, From the factory, you can order it with 15" wheel, so I guess it's possible to retrofit the option.
But the trailer is a bit large, ~7', so I looked for a 4x6 trailer with an RTT, Our current issue, the living space is limited, especially since we whould like to keep the center of Gravity as low as possible, so the RTT annex would not be usefull as living space when it rains.
I looked at the Jumping jack X4 trailer, main issue was the storage, would love see how current owner pack their camping equipment, I'll wish to keep everything ready in the trailer, so I only need to pack the food in the car and go.
So, I'm still looking for ideas. Cheers,
