the oldest version of the tents had carboardish laminate on the outer panels of the base,,this board used to get bad with weather,,
the newer model "last one manufactured" have those panels made with fiberglass .
the liquidation sell over a year ago was for the older model tents, not with fiberglass panels on the outside.
anyway ,,non of this tents are available anymore,,I have the last ones. like I sed before I was intending to take them to mexico,,but to much trouble with custums, so they gonna end up on ebay ,,sure they will go for way more than 500 ,, but will try to sell here first ,,,
ps. sorry about my english spelling.
