We live in Southern California and have a 2013 Unity TB model. We're thinking of getting a cover for it to protect it primarily from the sun. Has anyone gotten one and if so what brand and size? I'd also be interested in knowing how you install it; that is, do you use a ladder and get on the roof and drag it over or do you use a ladder(s) and install it going from side to side? Do any of the antennas need to be removed? Thanks.
