Thanks all for the replies. Somehow I got unsubscribed from the thread so I didn’t realize how many replies there were! Sounds like the AC should not be a concern, and yes it’s pretty darn important in Phoenix! Our van is black on top and silver on the bottom so maybe we would go with silver on the top for heat reflection. Seems like CCV is the consensus winner, I think we will call and get it scheduled. Talking to a few other owners and 1der I have been advised to definitely go with the high top version, seems less likely to regret having too much space I suppose? Though it might pose some parking issues as we are already 8ft tall - guess we will figure it out
Last question I had - we have a front runner roof rack right now, it uses legs to pinch attach onto the gutters but there are various other available mounting legs we could substitute. Would we be able to re-use that rack on top of the penthouse? Maybe the question is simply, how have others attached roof racks onto these tops? Do you have to drill through or do they come with some kind of track pre-attached to the top for adding a rack?
