Hi TamPham
I was in a similar position last year. We bought our RV, our first ever, last August. We rolled away "full-time" in November.
I work remotely M-F. My hours offer some flexibility, but typically I work a normal work day 7-4. I have calls on Skype Business and MS Teams daily. We don't use video though. Most of our staff live in very rural areas, so their internet is not as good as they would like. We've gotten used to not using video chat. My day isn't mostly meetings though. Most of my day is spent connected to servers via VPN and writing code.
Last December, I bought a Togo Roadlink, basically a Winegard Connect 2, and a 1 year internet subscription on AT&T. Unfortunately, they have discontinued that plan, so come December, I'll have to figure out what carrier SIM card to get. Right now I'm leaning towards the data plan from Cricket, but that could change by December. As far as hardware, this device is all I've used. It has performed great, and it's not even mounted on the roof. It sits on the dash until I decide what to do about future SIM cards.
When we left, we had our phones on T-Mobile. I think our plans allowed us 25GB each per month as hotspot data. When we arrived for a camp host position in FL, we found zero T-Mobile or AT&T coverage, so we moved our phones to Visible. We got another camp host couple to "party" with us, so we pay $25 a month for each line. The visible plan offers unlimited hotspot with 2 catches: you can only tether a single device at a time, and the speed is limited to 5Mbps. That speed is enough to do anything you could want, video chat, stream video, game, whatever. Some of my co-workers don't even get 5Mbps on their home internet.
We arrived in FL in March and left in August. From December through March, we had pretty reliable AT&T service, but we were not visiting a lot of parks. We were mostly in Phoenix/Mesa area or out in Quartzsite. AT&T in Phx might be the fastest place in the country based on ookla data. We never found a location where T-Mobile worked and AT&T didn't. Since moving phones to Visible and leaving our camp ground in FL, we have camped in many places with no AT&T at all, but the phone hotspot was usable on Verizon. There have been many the opposite too.
I am certain you will be able to meet your husband's data needs. I'm sharing my experience to help you create realistic expectations. As others have said, coverage will be the biggest factor. As an example, I'm in Spokane currently. AT&T via the Winegard device is providing excellent speeds. My phone, on Verzion, is also plenty fast. I was in Colville, 80ish miles north, all last week. AT&T worked great in the morning and evening, but would degrade during the day. Verizon was having a similar problem and had a worse signal where I was parked. The local cable internet provider was down, so I suspect those customers were using phones as backup data for kids schooling at home and working from home. It was still usable most of the week, but I had some heavy packet loss, and it would NOT have worked for a video call during that peak time around noon to 3 or 4. I joked with co-workers that it didn't like the heat.
You absolutely should proceed with your plans.
This is where I will sound a little discouraging, but really I'm trying to help you get to thinking about some things sooner, rather than later, and again, manage those expectations a little. Our reality has been a little different than the romantic vision we had last summer when we bought the RV. We're still happy with our lifestyle choice, but there are some realities of having to work on the road.
How many hours a week does your husband work?
Is his work a M-F business hours type of commitment?
Who is doing the driving?
Can he work while you drive?
If not, this could hinder your mobility somewhat.
My wife doesn't drive our RV (yet). I don't like to drive at night, so that makes it tough to drive outside 'normal business hours'. My job is based in WA, so that's easier if there are a few time zones separating you from "home".
During our recent drive from Flagstaff, AZ to Colville, WA, I worked a split shift. I would get up and work a few hours and handle any emergencies, then try to get on the road by noon and drive 4ish hours. Once we were parked for the night, I would get back on the computer and finish my work day. Granted, we had a deadline to reach WA, so we moved everyday.
If you aren't in a hurry, you can also plan to do your driving on weekends. Easy solution, right? Yes you can. Let's imagine a typical schedule...
You pull into your campsite on one weekend, and plan to stay 2 weeks. You spend the first weekend traveling and setting up camp. Your husband works during the week. Then you get a weekend to explore, then another week of your husband working. Then it's a moving weekend again, so you pack up and repeat.
Yes, you can explore in the evenings. Maybe your husband's work has some flexibility and he can do some of his work in the evenings (after the kids go to bed maybe?). I've found the limited resource is daylight hours. Keep in mind there are also all the other tasks involved with life on the road such as, RV repairs/maintenance, tank management, eating and dishes, laundry, fuel, route planning, etc, etc.
I'm not trying to discourage you at all. I just want to help paint a more realistic mental image of the lifestyle you're proposing. Is it worth the limitations? Yes! Just be realistic about what to expect. Your husband isn't "retiring and seeing the country".
Your kids are going to have an amazing experience. You're going to have a great time.
When are you leaving?
Since you're from WA too, I probably don't have to ask what direction you're heading. It's most likely south if you're leaving soon. I'm sitting in Spokane getting some work done on (and in!) the RV. Then I'm off to AZ for the Winter. I'm hoping to leave this weekend depending on if they can get the work done this week. The smoke might influence the route I choose. *cough cough*
wow. sorry. this got long. just noticed when I went to edit
OK short version. Get data connections on 2 networks, AT&T and Verizon. Now go. The rest you will learn on the way.
