Wildtoad, he's trying to mitigate the horrific air quality those of us in the west have been under for the last week. Wopachop, if I was out in the RV in this mess I would do the same thing. I would just go by the sound of the motor - if it's bogging too much then try something less restrictive. It's going to be a trade off, the more restriction the more potential stress on the motor but I would be trying to filter this lousy excuse for air too.
Actually the motor has less to do with more restriction, just like a vacuum cleaner speeds up when the nozzle is closed off. Motor failure from less air flow would be caused by over-heating. I think the OP has the right idea, but I would use the MERV-11 filter and make it much larger.
