I would go ahead and lower it. Most travel trailers are built a little high. Dropping a couple inches won’t hurt a thing. That trailer frame is strong. I always build skid plates on the back corners of all my trailers, so that they will just skid when going into a dip. No matter how high your trailer is, you can drag the corners at times. So fix it for that. My skid plates also are designed so that I can back up, even with my corners on the ground. I just spend a few short days reinforcing the rear portion of my new 24 ft enclosed trailer, because it’s LOW! On our trip to Bonneville I drug the back corners a couple of times. I have seen the whole back side of enclosed trailers drug off or heavily damaged due to dragging. I also adde a 3 inch square tubing right behind my rear fenders to protect them in case of a blow out. I designed it to accept a receiver hitch. I can use it for jacking or sliding it side ways with my winch, if I get into a jam. Just my experiences. PS: this pic was taken before modifications and the current hitch is a little higher, making the trailer level.
