Our company Tour d’Afrique Ltd www.tourdafrique.com is organizing a 4 ½ months, 8000 miles bicycle expedition that will start at the end of July 2009 in Rio de Janeiro, Brazil and finish at the beginning of December in Quito, Ecuador. We are looking either to rent/lease (or buy) two support vehicles: either trucks or vans that have been modified for expedition use and will be able to support about 30 participants. I would appreciate any suggestion where we could find such vehicles - preferably in South America.
