I would rather prefer the frame on C70 to be cut at least by 1m, so low saddle can be moved forward, and the frame will not pop out under any module, like it is now.
And I agree that saddle high should be removed from C70. It should not have an ability to haul heavy trailers.
just remove saddle for the options that are available for the C70. it does not make sense to give all trucks all options without checking weather its possible.
Alternative would be to be able to chop the frame on the c70, could be usefull with other addons as well. So including an option to shorten the rear overhang and moving the saddle forward would help.
Something i found limitating here is the inability to swicth frame wich is part of the problem faced now with addon who are not suited.
Even if some truck lose some addon it will balance the overall truck fleet to make them more complementary to each other, have their proper role.
