I can walk easily throughout with the slides in and I only have 2 drawers that are inaccessible when the slides are in - not a problem since I use those drawers only for rarely used items. Not having a walk around bed would get pretty old if using the RV for a long while. I've only got 30,000 miles on the V10 but it seems like a great engine. Hopefully pulling cyl. heads is not in the foreseeable future for my rig but if it is, I wouldn't be doing it anyway and I presume Ford dealers/mechanics would be competitive even if the work isn't fun. I've heard some expensive diesel expenses too.
