If you don’t wanna deal with heavy lifting, just rent a truck that fits your stuff or hire movers. U-Haul’s cheap for local moves, but for long trips, go with movers who do cross-country moves. Pack well and plan so you don’t stress.
I moved last year with two kids and a full-time job, and it was chaos. I got some dudes to help with the heavy stuff, and it made life way easier. If you’re stressing, I’d say hire pros like these guys: https://threemovers.com. They saved me.
