Yes. I did it and you can see pictures on my site. However, I got the new vent location of the pre-installed blocking from Jayco. Much easier (if it's there) than creating your own blocking. Also, the wiring was within easy reach of the new vent location (and they didn't put the wiring where it would be in the way while making the cut ).
My SLX came with 2 vents but no fans. So I installed a Vortex fan in the bathroom vent and added a Camco vent cover so I could leave it open in rain. Power for the fan came from a ceiling light just a few inches away.
In such a small TT, the one Vortex is more than adequate for ventilation.
