I’ve had my 7.3 l gasser Tremor for almost a year. It hauls my FWC Grandby quite nice. The only suspension mod I did was add Firestone airbags. The FWC Hawk is the more ideal fit for the 6.75' bed on Tremors, but I like the extra foot of length with the Grandby. I haul the camper with the tailgate down because it has a built in tailgate step I like to use when I dont want to pack a step ladder, and I like having the little 7” shelf that the extra tailgate length provides at the back of the camper. Comes in handy when cooking outdoors.
The trail control feature (think of it as a low speed cruise control) on Tremors is real nice for steep descents on rough and/or slick roads. The granny gear mode has come in handy for me also. I haven’t needed to use the snow/sand mode yet, but I’m sure that day will come.
Happy trails when your rig arrives. You’ll love it.
