There are all types of weights and measurements in reference to RVs, and sometimes, it can be confusing. What does it all mean? Below, you will find some answers.
If you are curious about your weight, many truck stops have scales, and they may be willing to weigh you. Also, be mindful of “weight distribution” in your RV. You want to try and keep the weight of your load evenly distributed, with the heaviest items over the axles. Also, avoid collecting too much unnecessary junk, and make regular trips to a thrift store along the way, to donate unneeded “stuff”.
