I also work remotely from my RV. I have an HP laptop with a wireless keyboard and mouse and a 24 inch smart TV that I connect with an HDMI cable for an additional monitor. I use a phone app called Adobe Scan which works remarkably well for scanning. I have Adobe Pro so I can create, fill and/or sign documents which I then send via email. In the rare event they need to be printed and mailed, I send them to my assistant (my DIL) who works out of her home office. We are boondockers so I use a Boost mobile wi-fi device called a Coolpad. I get 50g data for $50 a month. It connects to T-Mobile towers. In the event we can't find one, I use my phone mobile hotspot because Verizon is everywhere but I only have 10g a month on it and extra gigs are very pricey. So we choose our sites by whether there is T-Mobile tower in range.
