I am not sure where I saw it on their blog but they did have a frame failure of some sort not too long ago, just wondering if anyone knows the reason and the result of it all, was it mount issue or some other issue??Before leaving for a multi-month drive around Europe and Asia, Gary and Monika Wescott did some preventive maintenance on their iconic Turtle 5 camper. It turns out that their torque-free camper mount was designed and built 10 years ago by Midwest Four Wheel Drive, the company that builds the Bigfoot monster trucks. Gary and Monika paid them a visit to inspect and lubricate the camper mount.
The mount attaches the camper to the F550 frame in three places: two behind the truck cab, and a third on a crossmember behind the differential. The rear mount is pivoting, allowing the rear axle to tilt without a affecting the camper. Read a little bit about this feature and see a photo of the pivot pin in Gary's blog post.
Putting the pivot at the rear of the truck chassis is unusual. Most three point designs put the pivoting mount at the front of the camper, and mount the camper to the frame in two locations close to the axle.
