Well, dealer finally weighed it.  3680...dry...just a little off from the 3210 on the inside sticker.  I turned it down, not heartbroken as I really didn't want the 11 ft length hanging off the back since I tow. Would rather have a 9.5/shorter camper.
Since I'm coming to the reality of 19.5s, would rather have a smaller slide...like EC 850. AF 811. 910FBS, Maybe Lance 995. Easier for the dogs to have some floorspace.  Not in a big hurry anyway unless something falls in my lap like this one almost did.
Thanks for all the advice.
