Yep, you have to squeeze through the cabinet door under the bed and remove the right panel to the water pump/heater area. The filter is attached to the back wall. I'm not a small guy and changing the filter is a pain. I have cuss words with the engineer that designed this filter location every time I change the filter. I hope he/she can hear me!
This is the only thing I don't like about this rig. Otherwise 99.9 percent satisfied.

I put a new filter in each spring when I changer over from winterize to ready to go since I am in that area doing the waterheater bypass.
After three years and many many miles we still love our little Jammer.
