My 2012 Merc is 5.3T twin wheels. It's like a small truck underneath .Insurers never ask the weight.
With a Fiat 3.5t, 3850 is the max after that it's the Maxi chassis.
Some of the older Mercs you could got up to 4t but the new FWD is a bit of an unknown beast. The 3.5 can go up to 3880, they also do a 4430, I suspect that will have upgraded springs and shockers.
Is there a difference ,yes,The first number "3" denotes weight category so 314 can be up to around 3850Another question, ....considering new motorhome. merc 418 chasis 4.5 . Is suspension and undercarriage stronger than 314 , 3.5 tonne. or is it just paperwork. Can this be done retrospectively? as its quite a bit more cash for the 418.
Yes but you would have very little payload so probably wouldn't be drivable legally.so i presume a 4.5t can be downplated to 3.5t should prospective buyer not have C1 ?
