Red Pennant Insurance

I find it hard to understand why Red Pennant Insurance only covers caravans with a shipping length up to 24ft (7.32mtrs), without an additional charge. Looking at several makes of 4 berth caravans, they are 1-2 ins longer than 24ft. Is it Red Pennants intention 
to penalise families for 1-2 inches of extra lenghth? Why not increase the length to 24ft 6ins (7.46mtrs), to cover all four berth caravans, then the additional premium would only be on twin axle, larger caravans.
