Hi I have a 2015 Rav4 FWD. I'm looking at upgrading my camper I currently have a pop-up and it pulls great with just a little lose on fuel. I would love to upgrade to a small self contained the weight is the issue. The camper I am looking at has a tongue weight of only 400lbs but the total weight is 3,000lbs. The hitch says it is rated at 3,500 lbs. My question is I saw on here that the Rav is rated at only 1,500 lbs. So does it not matter what the hitch is rated at?
