This is the most recent, closest thing, I've seen to those...

I believe that might have been discontinued by Lifetime and there's only a few remaining in stock. It was also sold by Costco, they went out of stock in Canada here, otherwise I might have been tempted to get one.
Edit: Though I guess if you sit there an analyze it, you're getting about a $1000 utility trailer and $500 worth of tent for that... buuuut it's hard to do it custom for that. The direct buy from China types of sites, have tents available that are intended for use with small trailers. Generally, they are more of the fold out to the ground type though, Europeans and Australians seem to like those okay. You might need to get a tent first (Expect 2 months surface shipping) and play around with it on stacks of skids or something until you figure the ideal trailer to make for it.
