Sorry I have not been on the forum in a week. I am the owner of a 2015 Spartan 1032. Here are the answers to your questions if you didn't find out from anyone else already:
1. There is a slide out pantry next to the frig.
2. Yes you can access the frig with main slide in through the rear door going in to the garage.
3. No, sofa is fine for us.
4. Fit & finish was good. Just a couple minor things that the dealer took care of under warranty.
5. Very few items needed repair after PDI.
Our Spartan has been very good so far after 2 years of use. The tires that come standard are Towmax aka Blowmax. I replaced them last year with GY G614's & sold the original blowmax's. The brown nose cap started fading at the top. I found this to be a common complaint of Forest River RV's with dark caps. After it being out of warranty by almost a year, Primetime has authorized the dealer to paint the nose cap under warranty which is due to be done in 2 weeks. I love my 1032 but most likely will not get another 5th wheel with a dark cap due to the heat it attracts. I always try to park with the nose facing north if possible in the BLM & NFS places we like to camp. I have had quite a few people tell me they wish they had looked at Spartan's after looking at mine and I would definitely buy another when it is time to move up.
