Tough question! I feel like everything we are putting in our bus is a must have!

1. Solar panel: no matter where you are a solar panel system is sustainable energy at no cost aside from installation!

2. A good kitchen: cooking for me is fairly important and I didn't want a simple kitchen for my bus so I had one made with ample space for a chopping board aswell as various bowls for marinading.

3. Steering wheel knob: when performing "interesting" manoeuvres the best item is the steering wheel knob.

The views and the comments you receive from people are astounding! But jokes apart, one major advantage has to be the fact that you can travel wherever you want without having to worry about where you are going to sleep/eat/live, the bus is your life, your kitchen and your bed aswell as your best friend! No more hotel fees! The fun is another point, it is such a fun and exciting experience. Personally I prefer using a paper map with a chance of getting lost somewhere and discovering new places, no motorways, only scenic routes!

I would have to say a disadvantage is if that you don't trust your bus 100% to not break down. You can expect something to go wrong somewhere and that can mean having to pay a mechanic to tow your bus and get the parts changed. Another point I have heard of is temperature during winter, Though this one isn't applicable to us as we went for a double insulated interior in order to not lose any heat. Many Buslife friends we have, have complained about cold mornings cold showers (unless you own an electric shower you can hook up).

I've joined as many Volkswagen T3 pages as possible from Reddit to Facebook to Instagram pages I follow. Through these groups I have had amazing feedback from helpful strangers with links to parts and suggestions as to what issue I may be having. I'll name the websites I use in order of purchases made there. Serial Kombi, Mecatechnic, Heritage Parts, EBay, and Vwbusshop.de.
