Yes the GVWR is really about taxes. One of my former co-workers owns a fairly new Chev K2500HD extended cab which has a GVWR on the ownership of somewhere around 6,000 Lbs (I can't remember exactly what it was). He was pulled over by the MoT and given a warning for being over weight while hauling an EMPTY car trailer. The MoT guy told him he would be over the GVWR if he had no trailer but three passengers in the cab! The MoT guy told him he needs to change his ownership to reflect a higher GVWR which = a higher licensing fee and possible annual inspection depending on the GVWR declared. If I remember the advertising, these (or the 1500's ?) trucks have an actual GVWR of 10,200 Lbs, which would be on the border of light commercial in Ontario and require no annual inspection, but would have a higher license sticker fee. I believe up to 7200 Lbs has the same license cost as a car. If it wasn't about taxes there would be no extra charge for higher GVWR. And in Ontario the condition of the roads indicates to me that license fee and road taxes are not applied to the roads.
Mr Lang, would it be possible to let the forum know what the frame specs are for a model 1433 truck? My frame is ~210" long including the extensions at the back. Thx.
