I think N &b have called the market wrong. People will soon realise that sub 3500kgs are not fit for purpose and that there is little point in taking a C1 when for the same money you can take a C. Sadly by that time their reputation will be diminished.I think composite materials are OK, particularly carbon-fibre but they have to use different fixings.
At N&B, despite advertising Smove and iSmove at MIRO under 3.5t, the then senior salesman Jurgen Bath(since retired) told us to our face we do not sell a MH under 3.5t, because I think he was taking into account extras like awnings etc. and knew they are not viable at 3.5t. The question was asked by my other half who likes our N&B quality but is resisting taking her C1 licence.
