No TD for me (yet), as my requirements were/are:
1. Offroad
2. Less than 1K dry
3. Sleeps 4 + a 100lb dog (the tough requirement)
4. 15-20 gal water storage capacity
5. Standing room.
6. Low height when towing (drag, and to avoid being tipped into rocks/trees)
Trailer #1: A 4x8 HF, shortened to 4x4, and with a 2000lb axle (to get 5x4.5 bolt pattern tires). Built a bed for stuff - just threw the tent, coolers, etc in there. Needed something bigger than just the jeep. Think M416 full of camping stuff.
Got tired of sleeping on the ground, took a bit-o-time and came up with trailer #2:
A pic to get idea of it's really small size (5x6) and the TV:
Now I'm tired of the tent, looking to do something hardside. Guessin I'll make a few designs and post for comments.
