Buying a pre-built campervan or commercial campervan ("Class B") would seem to be a real win. In practice, though, there are many advantages of building your own.

Especially after the surge in interest in RV and Van travel that began in 2020, the quality of pre-made vans and RVs has dropped precipitously. It's gotten to the point that even RV dealers themselves are fed up. The amount of money that you'll pay for something of extremely questionable quality is astounding, with top of the line Class-B RVs pushing over $200,000.

Advantages:

• quicker
• easier in the very short term

• much cheaper
• you install what you want and are not stuck with what someone else wanted or thought you might want. You can make it as simple or complicated as you like.
• you put things where you want them
• you control the quality and specs of the components
• you can fix things on the road because you know where they are, what they do, and how they work
