As has been stated weigh it as if it was loaded for a trip best if you can get s weight for each of the four corners but at least for the front and rear axle besides the overall weight. Besides sitting your tire pressure you need to see if you have at least 80% of the front axles rated weight if you do not you can have handling issues. All weight behind the rear axles will take weight off of the front so that is why it so important when you weigh it you have it loaded as if you were going on a trip including yourself and passengers riding where they ride when traveling. Then if you still have handling issues alignment. IMHO always do the simplest cheapest first
