That is a nice setup JeepFreak... you said it's solid when lifted with just those 4 corner points of contact?
I guess I need to talk with my welder
Here is my setup. The RTT can be left in the lower position for travel or if the annex is not needed or lifted to full height, around 6'8" off the ground for the annex. The lid to the trailer can be opened easily whether the tent and annex are deployed or not.
