We have a 1999 8404 with 2 slides. It has a fair amount of room If I was F/T with kids I would definitely want a bunk configuration. How old they are may have some bearing from others with more experience. I swapped out the Table and chairs for a convertible flexsteel dinette. It works really nice but is a small pain to pack away every morning and fold out every night. We have only spent a week at a time in ours.
Typically it is just DW, myself and 15 yr old DD. Two times we have had 4 people....I was the only male
. Let me just say allow for lots and lots of primp time
.
I can't speak for the Alpha, but am really happy we have all the extra bells and whistles on the TM. The 325 HP in ours is ok, but I would like a 450
.
Be sure to let us all know which way you decided to go.
