IMHO, there isn't a whole lot of difference in brands...I've had covers from several manufacturers. I'm currently using one from Adco, the SFS AquaShed version. I've had it now for two years and it is still holding up fine. I've got a little rub spot on the roof panel fabric where it flapped against my Sensar IV enhanced antenna, but, it hasn't worn through and I've now changed my antenna to the much smoother Jack antenna, so, I expect to get another couple of years out of it before it needs replacing. I would/will buy another cover from Adco when this one wears out.
