..... had to chuckle at your title, "....instantaneous G force..."
....my concept would be cruising along and hitting a brick wall (instantaneous G-force). A speed bump at 30 MPH would be a gradual in comparison (hopefully, your shocks are tuned properly for the load & driving surface: offroad or pavement) :B :B
....Sorry. OK, back to the program...
On edit:
I don't know if shocks can be tuned for both extremes (and I'm not talking about off-the-shelf consumer-grade adjustable Ranchos)? I find it hard to believe that a shock (any shock) can be tuned to work properly both on smooth paved road, and the next moment, on the Chaco Canyon tooth-cracking chop-chop. Are there any Baja Score 1000 mechanical engineers working with a team that can give us a 600 level university class on this subject, on this Forum?
I've read about truck campers splitting in 2 (well, almost in 2) after doing severe offroading (offroading on terribly unimproved roads). How many 5th wheels, or tow trailers are pulled on severely unimproved roads? I think that truck campers as a "genre" are driven far more on terribly unimproved roads, and the excessive rock-and-roll (roll/attitude/centripetal/centrifugal) therefrom translates absolutely mirrored but at high altitude above road, obviously, through our truck's suspension (ie. we get a little more adventurous with a truck camper, and perhaps don't think twice about taking our rig along questionable trails/gravel roads?). So, the question would be: how do we make our TC rigs behave like the suspension under a 5th wheel/tow trailer? Is that even possible?
The other question is: the TC isn't welded to our trucks, and are often way lighter than our trucks, so our trucks are like a bucking bronco with a cowboy sitting aboard, always on the verge of being thrown off (my analogy). This can't be healthy for any truck camper structure...
