With over 2 acres to work with, have you considered building a garage or barn to accommodate the motor home and more? If I were to build a garage/barn structure, I would try to accommodate the largest RV as possible, even though I might not own one that big. It would increase property value. Others with RVs boats, etc. would find that of great value. If you can build it to accommodate over RVs, you could rent space inside to recover some construction cost and your real estate tax hike....pay for itself, maybe even profitable.
