Living full time in a box truck

it’s not a plane, you do NOT need a headset to talk to a passenger while driving.

 

Most people convert a school bus to an rv. There is alot of information online regarding that. You may find it more economical and a better base vehicle.for your purpose.

There are likely some converted box trucks as well out there and likely someone has documented the conversion etc.

As for talking to the passenger, if the vehicle is in motion they really should be in the passenger seat beside tou so conversation is easy.

 

Used Uhaul trucks are much lower to get into and out of the box area. Most used box trucks you'll find are "dock height" and need a ladder or steps attached to climb up into the box.
Approximately from the ground to the deck/floor of the box.
Uhaul - 29" (inches)
Regular box truck - about 4 ' (feet)

 

I'd also research transmission gearing. Commercial trucks are geared lower in order to haul heavy loads, thus will burn more fuel.
@AModelCat knows more about that than I do.

 

Please never park at a truck stop. There is a big mismatch between trucks on the road and parking spaces for trucks. Some of us work for a living and not finding a truck parking space because Brad and Madison are playing adventure games is not appreciated. Truck stops are loud and very crowded, anyway.

 

the Van Life has absolutely no appeal IMHO.. I see a lot of down and out people trying to do what you're describing. Trucking is the opposite. It's a life full of working and paying bills. Although we travel and stay in our sleepers, it's a job and there's really no comparison.

 

If you are asking, don't get a 22 foot box, get a 16 to 18 foot box. Don't get junk either, you will pay in the long run more.

 

What kind of budget - all in, were you thinking? Are you capable of doing the modifications yourself?
