In these threads, I always say to subtract the cost of staying home. The difference can be negligable, door to door, depending on your comfort demands and normal lifestyle. The biggest expense is often logistical when not door to door.

As a truck driver, you might could hitch with a fellow trucker from home to start point and back.

$25/day for ride, camp, eat is quite doable. Less with discipline.

Low cost per day should not be a goal when touring unless dictated by budget. Whatever it takes to enjoy, hang the cost, is best. If that's a $100 motel room every night, so be it. Cost is emphasized often due to our normal 50 miles/day pace vs 500/day in a car. Much cheaper to cover ground in a car or with commercial transport, for most.
