Dang, that sux on the horse going threw the floor.
We (farm and ranch folks) usually arnt as concerned about our trailers being nose high as camper hauling folks. Its really hard to set your hitch in a level area with one load of critters and then it be different on the next. And of the hundreds of trailers running around, and the dozens that us and our family has, nobodys ever had trailer issues from towing out of level, that's why theres equilizers.
And yes, most of our campers dont compare $ wise to a nice Sooner, or sundowner with a living quarters.
Now this isn't talking crazy extremes. But 6" or so difference from front to back is no biggie, thats more common than level, from what ive seen.
