2006 Palamino for sale

At a neighbors house, parked under trees for 6 years, and exterior dirty....real dirty (Black).....one bunk end has been open on and off for days....the other bunk end closed, but material sticking out and water leaked in.....quick look, no visible damage.....but could not get a good look being we could not reach the bunk due to slide being closed and junk piled in the way The Slide doesn't work....owner sez "I think it's a fuse"....the entry steps are hanging and bent (hit by a snow plow)....the interior is nasty dirty with trash thrown around, mouse droppings, and stuff I couldn't identify. There was a torn up sleeping bag on the open, unsecured bunk end with a tea light candle ( makes no sense, unless you doing heroin or crack). The rear corner has been hit, and pushed in a couple of inches....broken taillight, and not sure if it's delamination, or from the hit, but something going on down that side of the camper. I talked to the owner, and told him, "Based on a non working slide, what is your asking price".....he said $8,300....slightly negotiable. what are your thoughts ?....should I bother offering $3,500 ??
