How much loss do I get with a 3 foot motorola rp-sma pigtail to pass through a wall?

Depends on cable type and RF frequency, plus length. The wrong combo, and all you get are 'standing waves'. RG-6 or better would be preferred. Check this link for low-loss pigtails.
Ensure that the pigtail is grounded only on the unit side, and not also on the antenna side. This can create a "ground-loop" effect, and pick up unwanted RFI from any nearby power cables or other sources.

Little loss on that, it is shielded coaxial... Should get 3m on that....

Awesome! I thought I bought 3 feet as I previously said but after re-reading the shipping info it will be 3M. All should go well then.
