Uneven Bearing Temp

Thanks for the replies. I leaned toward the nose high condition causing the temp. difference put I was not certain. When I worked in maintenance years ago the first thing asked was what changed, is anything different? In this case it is the truck. We have owned this camper for ten years and I never saw this before. I have looked at the suspension saw nothing wrong. I use high temperature grease and the temp. does not get anywhere near the max. The B&W hitch is at the lowest position and I am going to check about adjusting the kingpin to a lower position. It looks as if I do that I will have about 5 inches of clearance between the truck bed and camper. We are to the point now that we have a seasonal site and only pull it there in the spring and back in the fall. I know the roads and am not concerned about the camper hitting the truck with that much clearance.
