We received our Sunseeker 2650S about 5 weeks ago. We were very close to buying the Solera 24S because as me too as driver, itís a little smaller. Never drove a Solera, but have read enough to believe it does handle better and ride smoother than the Ford. We went with the Ford for three reasons:
Cost: $16,000 more (RVdirect) pricing: Based on 5,000/miles per year, the fuel savings required 15-20 years payback (depends on fuel cost and your investing skills). We didnít have enough information for the gas versus diesel O&M calculations.
Net Cargo Capacity: Solera 24S was 1,178lbs while the Sunseeker 2650S was 3,400lbs. Iíve read many people on this forum drive over the weight limit. It may be safe, but I worry about lawyers. Check this link out:
2013 Solera 24R measured weight as delivered
Towing: The car we tow (Mitsubishi Evo X) cannot be flat towed. So we bought an Aluma light-weight trailer Ė 1,350lbs. Tongue weight must be about 600lbs, so that leaves 578lbs for people, dogs, water, camping supplies, etc. - read above link fully for lawyer issue.
A forth reason for spouse (not me) was the folding bed in the Solera 24S. It cannot be fully utilized without slide extended and the mattress is "ok" as it must fold when traveling. When the slide is out, a foam pillow top solves all issues ( but it's not automatic, you must put it on). I have read several good posts on the two other floor plans when it comes to a good mattress solution.
In summary, first start out with your requirements based on NCC and Towing - you can't increase either without warranty and/or legal issues. Based on that, that will determine your options. Good luck.
p.s. I still wish we could have gotten the Solera 24S, but we can't leave home without bringing everything, and the Evo is not for sale!
