You dont need a big capacity bike or loads of money or the need to stay in hotels or even pay for campsites either to do extended touring.
I know I have said this once but I have loaded an MZ 250 up with an unbelievable amount of stuff travelling around France and Spain. Instead of my load getting smaller it got bigger because I (being a bit of a scavenger) picked up the likes of a full sunlounger off the beach and strapped that to the top of all my gear.

Heck on that trip (of 5 months) most of the money I spent would have been on fuel and ferry crossings.
I met a young guy from England in the Alps and he was on a Honda 50, loaded up with tent etc.

So you use whatever you want. -or can afford.
I did the same traveling around the USA on a 30 year old Honda.
Sleeping in a variety of places from behind trees, the sides of streams to grass verges on deserted country roads. In fact anywhere I could pull off and try hide me and the bike.
More than once waking up with frost on my sleeping bag as I was too tired after riding into the night and/or it wasn't viable to put my tent up so slept next to my bike with a tarp thrown over.
Want to know how much I spent in 6 months? - about 500 quid. Yes 500 quid.
Just do it. You dont need wads of money. If that was the case I would have never ever been anywhere!
All you need is a bit of food to eat and a warm dry sleep.
