I reached out to 3Gstore and here is information they provided regarding boosting a wi-fi signal within a campground and boosting a cell signal.
BOOSTING A WI-FI SIGNAL
To obtain a stronger signal from the campground WiFi, you can use WiFi WAN on a device like the Pepwave Device Connector IP55:
Pepwave Device Connector IP55 (2.4GHz Only) : 3Gstore.com. This device would essentially repeat the existing WiFi signal in order to use it as your own network. As a follow-up I asked, how much signal gain can we expect to get? This was their answer.
The Device Connector IP55 would use it's WiFi as WAN range of about 1,000 feet to draw in that WiFi signal, and repeat it to your devices. As for Signal gain, that is a bit harder to measure with WiFi repeaters. The range of the unit is often times a good indicator of how well the unit will work for you. If you're outside the "usable wifi range" of the campground wifi then this unit can help you grab the better signal. Overall we've been receiving positive reviews about the Device Connector IP55.
BOOSTING A CELLULAR SIGNAL
For boosting cellular signal, you could consider a Wireless Repeater Kit for your motor home. The two main options you would want to consider would be the DT4G, and the Wilson Mobile 4G.
The DT4G is designed to be used for buildings to give a room or a couple of rooms boosted coverage. However, many people have seen success using it in RVs/Motor homes. The negatives to using this kit are that it
1. will not boost signal while the vehicle is in motion, and
2. requires around 30' of separation between the two antennas. Depending on the RV this separation may not be possible, however the amplifier can be adjusted to require less separation. DT4G:

The Wilson Mobile 4G will work while the vehicle is in motion, and requires much less separation. However it will only give about 5-10 feet of boosted coverage, whereas the DT4G may be able to cover the entire RV. Wilson Mobile 4G:

I asked how these 2 cell signal boosters compared to the Wilson Sleek 4G Universal SmarTech III Cell Phone/Hotspot Cradle Signal Booster mentioned in this thread, whether all the options are compatible with Verizon 4G LTE, and if they meet the new FCC regulations. Here are their responses. The Sleek 4G could also be a valid solution. The reason I didn't recommend this at first is because you mentioned boosting phones and a hotspot. Using the Sleek you would only be able to boost one device at a time, whereas with the repeater kits above you could boost multiple devices within the coverage area. They also said that when compared to the other 2 suggestions, the Wilson Mobile and DT4G amplifiers have the potential to give you greater gain than the Wilson Sleek because their amps are more powerful. As for compatibility and the rules, the answer was, all of these items are compatible with Verizon 4G, which is also their LTE network and all their products are in compliance with the new FCC rules.
I hope the readers of this thread find this information useful.
