Wife and I are planning to full time for 3 years or more. We did this back in 1994 in a 40' American Eagle and had a great time. At that time we generally stayed in a park for several months moving from the north to the south following the weather patterns.
LT is not a tire rating but a category of tire. LT stands for light truck and as the name suggests, these tires are designed for trucks and SUVs. The label LT is usually placed in front of the tire size. The other common type of tire is a P tire.
Some light-truck tires follow the Light Truck Numeric or Light Truck High Flotation systems, indicated by the letters LT at the end instead of the beginning of the sequence, as follows: The tire diameter is given for High Flotation tires and omitted from Numeric tires. 2-digit number: The diameter of the tire in inches. x: Separator character.
