195/70 R15 vs 215/70 R15

[Van-illa]

I can finally afford to put tires on my new to me '95 Winnie. Here's my problem. Winnebago manual says 195/70 R15. My gut says Vanco 2 8ply 215/70 R15 (2271 max load) but even cheaper is the Vanco 195/70 R15 (1984 max load).
Keep in mind the GVWR is near 6000 lbs. I won't be towing anything, but I'd like to keep the sprung weight down to a minimum to prolong the life of its moving bits.
This is a very clean example which runs great, the check engine light is intermittent, with only 49k.
Thoughts?
And yes, I checked the stickies.
P.S. Anyone got a middle seat?

6000 pounds I would go with the d or e rated tire.

And the extra weight & inertia shouldn't affect anything? 215 is about 4-5 lbs. heavier than the 195
