Yes I do have that, had to mount the trip computer where the stereo used to be, but there are other options. Wife said "you are not getting it unless you can keep the trip computer" I would recommend to keep it because it controls bluetooth, head light reminder and auto off, and probably other stuff that I haven't worked out.
CB as in UHF radio? if yes then YES!! use it all the time, would be a good idea to get one if you don't already have one. You can get quite compact units these days with all the controls on the mic, meaning you can put the bulky part underneath the dash or seat. Try to get an 80ch though as they have just been released onto the market as the 40 channels are pretty crowded.
One of the best things we bought was these awning clips, they work really well holding down the awning especially when combined with anti flappers. We have been able to leave our awning out in quite windy conditions without any problems.
