I have a 21 4wd that I want to do the same thing to. Wanted the 6.2 and 10 speed and chevy thinks it should only come in 4wd. There was a member that did a thread on dropping a maroon or red late model, but I've tried to find it a couple of times. Hopefully someone sharper than me can dig it up.
Hips are a piece of cake. Had both fully replaced at the same time at 50 and was walking without help in less than two weeks. Have a brother that just had one done as an outpatient. You seriously lay on the table in pain, and wake up with it gone.
Make sure you watch the sun when placing your appliances. We have an ice maker and frig that get the afternoon direct sun and have to replace them every couple years. Never thought of it when we designed it.
