I've had my XVenture XV-2 about two years now, with somewhere around 35,000 miles and 500 nights out, and have to say it is the best investment in gear I have ever made.
Just finished up an eight month adventure in June from Maine to the borderlands of West Texas and back, with long stops in the Smokies, bayous and swamps "South of I-10" in Louisiana, beaches on the Gulf of Mexico, and slow-traveled across Texas to the the West Texas/Mexico border, where I stayed back country for seventeen weeks. With the XV-2 as foundation for travel and basecamp, I could stay out longer, power all my own needs, and have the gear and wardrobe I needed for all seasons and situations.
Couldn't ask for more in a trailer.
