Carnet options for long term storage of overland truck in southern Africa?
I'm after some advice regarding longer term storage of our old (left hand drive) truck and how this affects the carnet. We currently have our UK registered truck parked in Namibia. The carnet has been stamped when we crossed the border from Angola and it is valid until next December.
Ideally we'd like to store our truck somewhere in the South of Africa (Namibia, SA, Malawi, etc) so that we can use it for another trip in a few years time. Are there any other options other than flying down once a year with a new carnet, leave Namibia to enter Zambia (for example) only to go back to Nambia again?
I have heard that it's possible to get the old carnet stamped out and a new carnet stamped in (in Windhoek) but this still means I have to fly down every year.
I also know that some countries (i.e. Malawi) can issue a temporary import permit (TIP) instead of using the carnet. If I went this route, would I get problems when leaving the country in let's say 3 or 4 years? is there any validity period on a TIP?
I am planning to fly back to Namibia for a few weeks in a month time and wonder what to do.
Any info regarding good storage places and carnet options very welcome...
