A true four season trailer or as close as possible

I have been trying to buy a Northwood Nash 26X travel trailer. It's the best cold weather trailer that I can find. Extra strong frame, stronger / thicker roof with extra insulation, large insulated tanks with the furnace hot air heating them. I'd like a 2006 model.

There are two on the east coast at a reasonable price, but that's a long way from Alaska to make a quick run. There's one in the Spokane area but we can't come to agreement on pricing. And there's two in Oregon. I have to drive down to Washington at the end of the month and have no problem putting on some more miles, but I'm not really wanting to drive all the way to the east coast.

Since I'm not having much luck on finding a Nash 26X, what's the next best TT made for cold weather? There is the Arctic Fox 26X, but that's more than I can spend at the moment. I want to stay at about 26' - the 26X Nash has a separate bedroom which is what I want.

Can anyone suggest anywhere else to search? I've been using:
* Kijiji for searching Canada
* SearchTempest for all of Ebay and Craigslist
* A Google search on any Nash 26Xs for sale
* Even sent a request to Camping World a little while ago
* RVTrader.com
* RV-Trader.com
* RVT.com

Let me know what other cold weather trailer you could recommend.

Let me know if there's any additional ways I should be searching.

Thanks,

Bill
