I’ve never personally weighed it, it I think my tongue weight should be just shy of 300 based on specs from Shoreland’r. My 14 explorer doesn’t squat too much which has 1200 payload capacity and 5500 towing capacity.Depending what your tongue weight is, you may be fine with a leveling kit. I would suggest taking a measurement before hooking it up and then a measurement after it's hooked up. If there's enough sag, you may not want to do an exact leveling kit. Do like a 2" so you leave a slight rake then your truck won't look like its squatting.
,measure from ground up to both the front and rear wheel lips. On level ground of coarseI was considering a 2" level. What’s the best/proper way to measure the rake?
