Did you happen to ask any questions about over width being non commercial.
Your biggest concern will be road closure or restrictions ~ do to road conditions . When the passes get a bunch of snow the WSDOT sometimes puts restrictions on wide loads and oversized loads . Call this number for questions 360 766 6196 . This is Bow Hill Port of entry . I chose to give you this number because they are easy to talk too about
Wide loads
Towing a load and requirements
Scales
Securing your load
Anything concerning your towing the cat in Washington State
Anyone out there that is even thinking about towing a cat in Washington should call this number . This will be straight from WSP all the answers you need .
Something to think about .
Know your trailers weight empty
Know your trailers rated weight for hauling .
Know your cats weight full of fuel
take a look at your trailer tires find the rating
Example
10,000 pound rated trailer has four tires rated at 2910 psi (not air pressure)
this means your tires are rated for a load of 11,640 pounds
But remember you trailer is only rated for 10,000 pounds you can not exceed that .
If you exceed 10,000 pounds you can try and move your load forward on the trailer taking weight off the trailer and onto the truck towing the trailer .
If you decied to move your load forward putting more weight on the truck . know the weight of the truck on the rear axel empty and then add your new weight from the trailer tong weight . Check the sticker in the truck door jam to see you havent exceeded the weight rating for the truck rear axel . Some cat owners take the blade off or turn it as far forward as possible to get under the 8'6" requirement .
There is a thing called Tonage this is something you buy at DMV . Ask about this when you renew your tabs on your truck . You may need to buy extra tonage . Tonage is what the State Patrol is going to write you up for if everything else is in order and your not commercial . If you tow with a commercial truck expect to get stopped by WSDOT . Call the above number make your like simple they will explain it all to you .
Oh one other thing to think about IS your hitch rated for the load your towing ???? If I missed something , there are plenty of folks on this forum that will pipe in with a correction .
