I just pulled up the actual coverages and limitations for OR/ID and this has not been implemented. It might be only in the OP's region.
For states where the limit applies, it should be noted at AAA provider rates are about half of what most retail row rates are. Often even less. AAA rates always apply for member when they exceed their coverage limits. The $500 cap will cover about 200 miles of towing, so for a an RV+ plus member, this would be 2x 100 mile tows. This is important because some smaller providers will default to sending 2 trucks for a truck/trailer combination, while many of the larger providers have the equipment to haul a combination as a unit. So it may be worth it for a member to request a truck if this new limit applies to them or if they will exceed the miles covered in their plan.
As for other coverage options... It's difficult to compare coverages because most of the other plans advertise "unlimited" towing, but when you get the contract, the "unlimited" miles only cover miles back to the service provider or the nearest preferred repair shop. This is their preferred repair shop, not yours. If you want to be towed in a different direction than the service provider came from, then those plans have coverage limitations as well. This includes GS plans.
