Best way to mount cabinets for no squeaking
I am replacing the front cabinets where the tube TV used to be. I built 3 new cabinets. One is 8' wide for the front and 2 4'ers go on the sides.
The front cabinet really only can be mounted to the leading edge of the walls and roof. It extends forward into the space that the front cap/windshield creates without touching the cap or windshield. The two side cabinets can be attached to the roof and walls and the front cabinet.
My question is what do others recommend for minimal squeaking?
1) On one end of the scale, I could bold them solidly to everything. The front cabinet would be attached a few spots along the roof and also the sides. The side cabinets would be attached to the roof, walls, and the front cabinet.
2) I could attach the front cabinet only to the roof. The walls are 97" apart, so the 96" cabinet won't touch the walls. The side cabinets could be attached only to say the roof, or to the wall, leaving a gap between the non-attached sides and between the front cabinets.
or something in between
3) attach the front cabinet to roof and sides, and attach the side cabinets to just the walls but also put felt between the side cabinets and the front and put bolts to attach them that are not so tight as to prevent the side cabinets from moving relative to the front cabinet. In other words, no visible gaps, but movement is allowed.
I fear that #1 will make the wood creak as the whole thing is flexed. #2 just seems lame in that there will be gaps between the front and sides. #3 seems like a potentially dumb trade off between stressed wood that creaks and moving parts that squeak.
This is a DP that I find a hell of a lot more quiet and rattle free than the gas puller's I have rented in the past. This might mean that I can bolt it all together and unless I'm doing some offroading the wood won't be stressed. Or it means that any error, causes a noticeable irritation cause everything else is so quiet.
