Hi guys im new here ..be gentle with me

I currently own a gen 10 lariat f150 over here in the uk but looking to upgrade and get a Harley Davidson edition soon

Looking for info on what to look for any inherent issues etc with them

Rust issues places to look ??
Engine issues ?? oil changes ?? charger issues rebuild lifespan etc ??
do they have an LSD ??
best places to buy parts ? i normally use rock auto
Any normal places for wear and tear possible leaks etc
The more you tell me of what to look for or inherent design issues anywhere would be appreciated

thanks people
