The answer largely depends on your level of skill, knowledge, and patience. For those with a solid understanding of electrical systems and some experience with vehicle modification, the process can be a challenging but rewarding DIY project.
However, for the average person, it might be quite an ordeal, as it involves complex tasks such as installing solar panels, batteries, an inverter, and wiring system to power all the amenities you want in your camper van.
For those who find the idea daunting, there are many businesses that specialise in electric camper van conversions and can offer expert guidance and services. It might cost more than a DIY approach, but it saves you from potential headaches down the line.
