One other thing you may want to check.
Get under your trailer, look at the tag on the axle, and see what the capacity is. Our '83 27' Excella weighs about 5,600 lbs dry and empty. About 500 lbs of that is carried by the tongue, leaving about 5,100 lbs carried by the axles. The old axles were 2,800 lb capacity each, making 5,600 lbs. Add up water, food, food in the refrigerator, pots and pans, utensils, clothes, shoes, TV or TVs, computer and other electronic equipment, propane, added furniture, lamps, folding furniture, tools and equipment in outside compartments, solar, A/C..... Need I go on? You do the math.
I installed new axles with a higher capacity, giving us a little "breathing room".
