I am a retired RVer. I just added the wifi hotspot on my DX. I don't like paying the $20 but it was easy. Now I find out I can do it for free. I am not sure I can do it but others can. Too bad they don't make a senior citizen app.
Its not really that hard. Just need root access.
BTW, stay safe out there. My family full timed for over a year while building the house.
