Leveling trailer front to back for towing
I'm towing a 31' Jayco Whitehawk TT with a 2014 Ford F150 w/MaxTow and Heavy Duty package. I've just upgraded tires and wheels from LRC 14" to LRD 15". The new tires are taller by a half inch in radius. Prior to changing over, the trailer pulled fine and was slightly down on the front end; I don't remember how much down. After changing tires and wheels, the front end is down 4". Is this amount OK? I towed the trailer down the interstate and it towed similar to before, but a little bumpier ride probably due to increased tire stiffness. I have an Equalizer brand hitch. I'm wondering if I should raise the hitch head one notch (about 1.25")?
