For kicks, I input our 2007 2350 on NADA-RV.
The stated original MSRP of ~$79,000 is $9,000 less than the documented MSRP of our PC, so that figure is off by a lot.
Low Retail: $32,700
Average Retail: $39,400
I would hope that our PC would be worth more than average retail given it's preservation with indoor heated storage. It still looks new. Strange as it may sound but it even smells new inside. When I take it to our church car show on Father's Day weekend, many people think it is brand new. Obviously they are not familiar with the change in body style Ford made in 2008.
Our PC might be worth ~$50,000 but who would ever pay that much for a 10 year old Phoenix Cruiser without a slide out? Good thing our plan is to keep it till our driver's licenses are taken from us. At age 58, I hope that won't be for another 28-30 years.
One thing certain, if it got totaled or stolen, we'd get so little from an insurance claim.
