Currently, when the trailer is hitched to our truck (and empty, no horses), it does not appear entirely level. The back of the trailer is a smidge lower than the front. The difference is ever so slight, but it's noticeable if you're looking at it. I feel like I've read somewhere that it's important to have the trailer be entirely level (so that if you were to put a level on the wheel fender it would be perfectly flat). However, when I expressed this concern to our barn owner, she didn't seem to think it was a problem and told us that it would probably look different with the horses in the trailer anyway.
So, which is it? Do I go out and get one of those hitches that is a bit lower so that the trailer is completely level? Or do I just leave it alone?
