No worries on LT tires on a RV as long as you can get the load rating, I will go with LT on our fifth wheel next tire change. Having a single axle is great on tires as there is no alignment issues so you will need to replace them due to age not wear👍, now please tell me you did a bearing service? Safe travels and we will see you soon 🍻
