Snowman9000 - I liked what I saw. Quite a selection to pick from. All would be more stealthy than the pop-up. The pop-up I showed in my posting was purchased for my kids and grandkids. Only paid $500. The streamlined motorcycle trailer cost $3,500. The RV does not even know whether it is pulling either one. The secret is to buy something that attracts lookers followed by interested buyers. The purchase price then becomes a mute point as you can sell it anytime you want and get most if not all of your money back.
Here is another possibility -
The Chariot.
This one might cost extra if pulled into some campground -
Scamp 13'. These can be found in used condition. They also hold their value.
