We're just starting to plan a road trip around the Western US in August/September 2013. Our boys will be 5 and 8 and we plan to travel for 6-8 weeks. One of the first decisions we need to make is mode of travel.......RV sounds appealing but I'm finding it difficult to get an idea of costs. They vary hugely and I have no idea if the companies are reputable or not (we're in New Zealand).......so can anyone recommend and economical but reliable RV rental company? Thanks so much:)!
