After years of short-term, dry camping trips in a Callen shell- I've upgraded to a trailer for extended travel into Baja and beyond.
It's the smallest size (15' total) I could find that still has the amenities I wanted, and fits in the extended driveway (to avoid storage fees).
Like the Callen- this "FunFinder" has an all-metal frame and aluminum exterior to keep out dust and stand up to Baja potholes and washboard.
And unlike the Callen: I can stand up, cook, and even shower inside!
It has 2 propane tanks, and more water storage capacity vs. other designs, so should be good for longer, more remote travel.
Some owners add taller tires/bigger wheels and flip the axle for added clearance, but I'll wait to see how the "standard" set up works.
The concept is: If the road gets too rough, look for a safe place to set up camp, then use the truck to explore beyond the range of the trailer.
If I find a more remote campsite, I can still sleep in the truck for a night or two.
First trips will be local as shake-down, then plan to head south in early January- about the time the whales begin to arrive in the lagoons.
