It is an Isuzu NPR 45/155 Tradepack. GVM 4.5T and GCM 9.0T
Only problem is I can't find private insurance. So far every company either says no or wants to offer business. I have a qiote for almost $4000 per year!
I just bought an Isuzu NPR like yours for towing the new caravan. Again like you the quotes are around or above $4,000. I have tried numerous brokers and insurers and all came out about the same. Biggest problem is they will only insure it commercially.
Did you manage to find insurance? If you did who did you eventually go with?
