Wow AA,
Given the good work you've done on the cabinet latches and all,
suspect yours moves less than others !
I was surprised by the noise in yours as I thought our 38gk seemed like it was pretty well insulated from outside noise when camping!
the wind and road noise was something !
re your comment about noises in the motorhome... depends on the coach - we test drove a new Itasca and I was afraid we wouldn't make it back to the dealership it rattle and creaked so much
but the new to us Monaco is relatively quiet IMHO... but it does bob and weave and has quite a light show if going away from the sun!
