Well this sucks. I thought this was going to be easy. Get a smallish truck camper and don't push the numbers too much. Seems that if I want to be legal in B.C. I need a different truck. The only way to have a smaller RV for my quicker/easier trips with just my son and me would be a smaller trailer. I was kind of looking forward to something totally different. Oh well.
Getting plates in a different Province (Alberta) doesn't sound legal to me. Seems like it would just be better to run overweight.
But, the Washington thing may be something to look into. I don't LIVE there but I do own recreational property there which may make a difference. I have an address, house, pay property taxes, etc. I will have to look into that.
