As a small business (just me) I just started an ISP inside of an RV Park in Colorado. I pulled over 3 miles of fiber optic so that every site can have it's own 1 Gig internet hook up. I think this is probably VERY rare, but I hope to see this grow as more people are moving into RV Parks long-term and need high speed internet for work, education, medical support and entertainment.
At my RV Park guests can expect speeds up to 1 Gigabit upload and 1 Gigabit download. I provide WiFi routers so no equipment is required and it's less than $100.00 per month. This is a very competitive option in my opinion.
And I hope to create a standard around RV Parks offering wired Ethernet ports at each site. Some day at the pedestal there will be electric, water, sewer AND Ethernet ports.
Other internet parks that I've seen with "high speed internet" partner with an ISP that places an antenna on the RV, there is often significant setup cost and the speed is affected by wind and rain. Speeds are around 25/5mbps.
The state of Colorado has an initiate called Advance Colorado that has millions of dollars in grant funding to grow broadband internet access to underserved and unserved areas. They do not consider wireless or satellite service as "served" and categorize anything under 25mbps as unserved. So by that standard I would consider all RV Parks as being unserved.
In my research, I looked at every RV Park within 50 miles of Evans Colorado. We looked at reviews of the internet access on Google and other ranking services. As a rule RV Parks all advertise that they have free WiFi, but the Wifi is typically terrible and only accessible in some areas of the RV Park, 25mbps download and 3mbps upload.
Parks with good coverage often are thwarted by RVs with aluminum siding which wreaks havoc on WiFi signals. Even with modern WiFi technology, the most expensive antenna cannot overcome physics. More devices, more walls, weather, all contribute to signal loss and packet loss.
Anecdotally, a Comcast service technician related to me that in one park they serve with outdoor WiFi access points, when an Airstream trailer would come into the park it would take out the WiFi for ALL guests within that area of the park.
I believe that the only reasonable solution is to offer wired internet access that allows guests to put the WiFi signal INSIDE of their RVs.
When the WiFi can originate inside of the vehicle, this makes a huge difference.
I should add something about service. If you're living the nomadic lifestyle and working remotely I don't think that you should be expected to sign a term contract to have access to excellent internet. You should be able to pay your fee and get to work.
