I agree with Driveby
. Keep them with you for legal purposes ...but it's just not worth actually using them.
I say this each time this topic is brought up but it's always worth repeating. Yes, in some states such as Oregon and Washington, you do need to have chains (or an approved alternative device) on-board
in certain stretches of highway (interstates included) during the winter months.
However, it's just not worth using them on a Class A motorhome unless you absolutely have to because of having to be somewhere at a certain time. You have a house on wheels so if the road conditions are such that the "chains required" is in effect, just pull off the highway in a safe place and wait it out.
It's a top priority in mountainous states to keep the interstate highways open. They will do everything possible to keep the road plowed and open. If they have to close the road because of conditions, they want that to be for the shortest time as possible. There's lots of commercial traffic depending on the road being open and accessible. Therefore, the "chains required" conditions or even closing the road completely will last for as little time as is possible.
Some Class A motorhomes do not have the clearance to run link chains so make sure you have enough clearance to use chains on your Class A if you do intend to use them.
Also, be aware that if a link breaks, a lot of damage can be done to the body of your rig ...steel links beating against fiberglass especially isn't a good thing. Sometimes a lot of damage can be done before you realize you have a broken link and get stopped ...not always but there are times you won't know until a lot of damage has been done.
And, it's not fun for most of us to be putting chains on a vehicle with large dualies. Most of the time it will be freezing with snow coming down and could be slushy and wet on the shoulder of the road as you installing or removing chains. I'm a former commercial driver and although I got pretty good at doing it quickly, it was never a real "fun" thing to do.
For others contemplating buying chains, you may want to look into the AutoSock idea that Unplanned
mentioned (HERE is the thread
that was referenced) as they are approved in 48 states as a chain substitute. At least they are easier to install and remove if you just have to be somewhere when the "chains required" is in effect. Just remember that running the AutoSock on bare pavement for just a short distance could ruin them.
