Maybe you can help us

I think the most economical combination to travel/camp in is a small Class A with a small, light tow car. It will be more economical than a truck towing a trailer or 5th wheel especially if you stay in one spot for a month. I would choose the A over the C because the MPG is similar(7-10 mpg) based on weight but you will have more room inside, more storage outside, more FW capacity,and usually a better heavier duty chassis. Being young back packers I would look for simple,small,a functional floor plan for your needs because you will probably enjoy camping outside under the awning rather than watching a flat screen TV inside. Most folks responding are probably older like myself so what may work for us my not be good for you at your age. I stopped back packing 10 years ago but really enjoyed it when I was younger. I would look at short A's from 2006-2010. It will have the latest chassis improvements and be cost effective. Good luck in your search.
