Depends how you will use it:
- Seasonal site where you never (or rarely move): Get PVC pipe and do a semi-permanent install. Do keep the valves closed until at least half full. If you leave the valves open, the solids don't get pulled out and pile up in the tank until they block it.
- If you are staying longer term but moving around, getting the hose supports are nice as they stop sewage from sitting in the hose and smelling (yes, the smell will go right thru the hose if it sits.
- If you are pretty regularly on the move (rarely staying more than a week): You just hook up to dump, so no real need for supports.
Consider hoses as disposable items. They will fail periodically (even the expensive ones).
