It sounds like you’ve got it pretty well sorted anyway as far as general “touring” goes.
If your going to be on dirt roads, you may want to consider an air compressor,, ie; if it’s wet, you may want a little more traction by lowering tyre pressures, or it might be really rough or rocky, also good to lower, and of course, sand.
Have a gander at some of the build threads regarding D3/4’s and see what they do with their machines,, this will give you a good idea of how people have set up their rigs etc.
You’d best be getting some experience in too

Just sayin’

Should organise a couple of trips with others on here. It’s an extremely capable car out of the box, but there’s nothing like doing a couple of trips with others to instil full confidence

As for the motor,,, if it’s all been done properly through the right channels etc, I wouldn’t stress about it at all.
Hope this helps.
