I have a question regarding towing on my 2004 V8 4Runner. I have the factory tow hitch that is rated @7,000lbs. I would like to tow a camping trailer well within this capacity. My question is do I need to upgrade my springs/shocks or even a lift kit? I see a lot of posts on here with aftermarket lift kits. I am just concerned with the tongue weight that it puts additional weight on the rear axle. Would a lift help this out or am I okay with original equipment? I do plan on purchasing a WDH as it was recommended from the trailer dealer. Sorry if I placed this post is in the wrong location.
