Which to own- a New Mid level 5er or a older High line 5er

My thoughts were to invest on a used Hi-line Model with a plan on doing some upgrades/repairs. RV's can have good bones but there are still wearable items that will need to be replaced- Bedding, Furniture, tires and suspension but at a cost of 2-3,000$ and then a professional detail on the exterior you have a real nice unit to enjoy for many years..
