Lance 1685, and hardly a throw away trailer. Lance also has good service, and one of the best warranties out there. Lance has a lot more storage, and the slide out makes a big difference in living space. The AS is more than $15,000 above the price of the Lance, probably closer to $20,000
I narrowed my choices down to the Lance, and AS, went with the Lance, I just couldn't justify the price of the AS.
I do like the cool factor of the AS though.
Lance 1685 loaded, 4 season package, etc., should be around $26,000, depending on transportation costs.
I'm towing with a 2011 V8 Pathfinder, tow capacity 7,000 lbs, I wouldn't want to tow it with less.
Go with the Lance, and use the money you save to get a proper TV. Your 4Runner is not enough truck!
