Our Newell does not have jacks. Hence we use leveling blocks. Do I need blocks under both of the dual tires, or is it sufficient to put blocks under one tire on each side? Also will it damage a tire if it is partially riding on a block?
When blocking your rear tires I would recommend either 2 blocks(one for each tire) or one large wood block that spans the width of both tires. If you block just the one you are essentially putting all your weight on the one tire and I would not trust that. This is of course my opinion as I'm sure others will respond with additional information.
