If one province won't give you an A2, try another province, eg Vung Tau.
Minsks are actually a lot of fun. These days they have mostly been replaced by other bikes however. Google Minsk Club Vietnam.
Camping in VN would be seen as a bit odd btw. There is always somewhere to stay, even in out of the way areas.
Hanoi has quite a few tourist oriented petty rip-offs. This is not typical of the rest of VN. Problems are almost always avoided by clarifying the price beforehand. And don't get in no- name company beat up looking taxis. Reputable taxis are new and in good condition.
