Advice for newbie with 2011 2720 water damage?

[Hermey]

Hello All,

I hope this message finds you well. I have been following your forum for some time and have found it to be very helpful as I am looking to buy a 2720 or 2417. I found a 2011 2720 SL for sale and the seller has been very honest with pics and any damage. I would have to drive a long distance (10 hours) to view the camper in person. I am concerned about potential water damage as indicated by the pics and what the seller has indicated is sponginess in the floor in front of the door. My questions are:

How concerned should I be about this? I know there is a lot of aluminum in Trailmanors. So, is this just an issue of peeling up and replacing linoleum or am I in for larger issues such as wood rot and water intrusion into foam?

Also, if I move forward how much should I discount my offer from their starting price of $10,000?

I have attached the pics of:
1. the floor by the door where the linoleum is bubbled up (area of bubbling and sponginess is the area between the door, the flip flops and the paper towel)
2. where water wicked up the cabinet
3. front view of linoleum bubbled up and then peeled back
4. the roof vents that is leaking


Thanks in advance for any advice you can give to this newbie. Your advice will likely determine whether I make the trip to view this.
