scraping bottom

We are brand new owners of a 2006 2720SL. Entering into even the most gentle of drainage swails, we hit bottom with the front of the TM (below the propane tanks). We've read much on this forum about lift kits, bigger tires, WD hitch, raising the tow vehicle, reversing or replacing the ball hitch on the tow vehicle etc.

We are towing with a Nissan Frontier and our ball hitch drops about 2 inches. It all looks nice and level currently, just too low. We do not have a WDH. The TM came with the brackets and the previous owner says we are welcome to the bars but we can't get them for 6 months as they are traveling. We don't feel we can even travel to get them with the current scraping issue.

So our question is ... of all the options mentioned above that will fix the issue, which is the first and foremost that we should do now? We are willing, just want to do the right and smartest things first.

LOVE OUR TM, LOVE THIS FORUM!! So happy to have found it.
