Truck insurance for commercial transporters up to GG 3,5 t

Own searches in internet portals for insurance, direct mail request at KRAVAG, inquiries with an insurance broker, all effort in vain. Does not insurance in Germany any more transporters up to 3.5 t? High damage rate, high fluctuations in the courier industry suggest it. I get these months a new transporter (commercial freight transport) and for this I would like to have an alternative offer to the existing one. Only with whom, who insured at all what?? Less cost-effective?? With the expected annual premium (provision) all field staff would have to run my hut!? Who knows another insurance that does not shy away from taking a risk? You know them…insure? yes, yes, concrete under water against fire… Storm and theft are unfortunately not insurable…
