You will find that in about 90% of homes that have a guest bedroom, that room consists of old mattresses and bed furniture that people dont want to use themselves but expect guests to sleep on. Do yourself and future guests a favor.....throw it out or burn it. If you cant sleep good on it why do you expect someone else?
I buy the cheap stuff at Costco for the house and trailer. I've been living in the trailer for the last 13 months (on weekdays). If I was going to have a problem by not using the 'special' paper, I should have had a problem by now.
Get an adapter that screws into your city water hook-up. It will blow out water in the pump too. Then just add a bit of the pink stuff in the p traps and let the pump suck up some too. Then you'll be good to go.
I use the RotoChoks between the tires. They work regardless of whether the tires are on leveling blocks or not. And I chock both sides unless it is just a quick overnight stop and the site is very level or we stay hooked up to the truck.
