I really appreciate all the responses so far. My friend did not get the OTR model and dose get some help with his WeBoost, but not like he was hoping. Not sure I want to gamble with that much money at this point. Maybe this will help others that read this discussion decide if the WeBoost is right for their application or not? Thanks all with your thoughts on this topic! Vance.
Hello there. I have an off grid workshop (eventually our home will be completed and reside next to it) and I use the Weboost Connect, links below, and use a Weboost DC power supply converter since we use 12v right now as well, also link below. I wanted to mention this in case you didn't realize you can use the standard home or office Weboost products with the DC converter (they advertise it as just for their 'mobile' type setups, but it doesn't matter).
In my situation our little area is in a small depression where we get no service. If you go up a bit higher you can get maybe an intermittent bar or two. The Weboost Connect comes with a directional antenna (you could buy the Weboost Home omni antenna version if you wanted it for your RV) which is the key difference in really amplifying your service. It also comes with an inner antenna which is good for a normal home size, unlike the mobile inside antenna's. We went from no service, to LTE and able to watch any streaming service you want. In my case it's usually a Youtube video showing me how to do something while i'm out there working.
I found where the local cell towers were, put the antenna on a 30ft pole, and aimed it towards the best tower by using the number you dial (for newer iphones) to get into the right screen to truly see your signal strength. You could make a removable mast that could be taken on and off your garage and put on your RV and extended when you parked somewhere.
