Hey all

I'm currently looking at getting my first 5th wheel, nothing special, just affordable. I have one picked out that I like but had a couple questions.
First, I cannot find this trailer on the nada guides so I was hoping some of you could suggest a price that I could offer to the seller (he's asking $6,000). I would need this towed and parked but it is only a 20 mile round trip from where it is, hopefully seller could do that.
The flaws, that I have seen, needs new couch, oven doesn't work but burners do, carpet needs deep cleaning or replacing and needs a new stereo.
I have walked through it and it seems in decent shape, no visible water damage/leaks, plumbing and electric are good, anything else to look at?
Thank you for any help
