I have a 2001 Marlin 390 diesel pusher that I've had for a year and have done some extensive remodeling to it. Here is the link: zzjea's photosets on Flickr
I would be interested to know who else has one like it or one the other models too. Mine has less than 30K miles and is now almost better than new. We are really happy with it.
I believe it was only made in 2001 and then was merged into the Tradewinds the next year.
If you have info, pictures, work done, issues, etc., I would be glad to hear from you.
