My 2000 model 2 slide coach had 315's on the front when I purchased it with 165,000 miles. So, those size tires served owners well for years. Also, the tires were well within the weight limit. However, I was not fully comfortable in all driving conditions with the handling, and did not like the roughness due to high air pressures. After upgrading to 365's, there is a noticeable improvement in ride and handling. If you purchase a coach with 315's, I would drive it a while to determine if you want the upgrade.
Concerning the basement vs roof airs. Once I installed the upgrade on my basement airs, I have been completely happy with performance and air flow. While roof airs would offer more basement space, I would just clutter it with unnecessary stuff I suspect. We are full timers and have plenty of storage now. One more thing, on my vintage of coach, to me, roof airs would cause more unsightly stuff on the roof. I prefer clean lines. The newer coaches have awnings on the roof instead of the side which hide roof airs. Bottom line, I would not shy away from a coach you like due to 315 tires or basement airs.
My .02 cents :-)
