No personal knowledge but have always heard good things about them. There is an owners forum here: http://autos.groups.yahoo.com/group/alfaseeya/

We fell in love with the Alfa See Ya in 2004.  We continued to look at others since then, but when it came time to purchase, we got a new 2006 40' DP in May 2007.  We have lived in it ever since, and just 2 weeks ago we hit the road (I finally retired 9/7/07  YEAH!!!!)  We have found it very easy to live in while parked, but we were nervous about the travelling.  Well, I am very pleased to tell you, we have traveled 1300 miles in 2 weeks, mostly thru mountainous country in the western states.  Our worst worry was in Oregon, getting from
I-5 to the Pacific Coast Highway.  Only 60 miles, but 2 lanes, mountains, and winding roads.  The rig handled like a dream!  One thing that seems to plaque Alfa is the big slide motor.  On a 2004, has that motor been replaced?  Otherwise, we are extremely happy with our decision.

nooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!!!!!!
Stop, please please please don't waste your hard earned money on that rig. You will need to overcome the 'glitts and glimmer' of the whole thing and look at th big picture. All that plastic rubbing making noise going down the road, it's all for initial show. The basement air in that thing is totally messed up too. I seen an Alpha sales video where they explained how their system ''works better than rooftop units because cold air naturally rises'' anyway!! All of us in service hit the floor with laughter, as the sales guys just looked at each other confused. My first experience with Alpha Tech support told us that its normal for the unit'' to take 24-48 hours of cool down time, so just tell the customers to get a hotel room for the first few days while their unit cools down enough to be comfortable''. And the best for people camping in the south in the summer''the coach wasn't designed to be used in weather over 95 deg.''. This is one messed up company, out of the last 6 I've seen go, all had rear pass. side slide room issues, we replaced all the main A/C control boards and 3 thermostats, lots an lots of broken tiles from the chassis flexing, and the absolute best thing I just saw on the new 2008 that just went out was they installed a junction box at the drivers side rear for none other than, thats right everyone a third ''optional''air conditioning unit just to keep you from dying of heat exhaustion as you sleep. It's up to you but i guarantee if you just gotta have that extra 6'' of head room ''I'll SeYa at the dealership""
