The collar that holds the shower head to the hose cracked and we need to replace the hose as a minimum. Question: Are these hoses universal with household showers? I am not considered a handyman but since RVing the last two summers I've gotten better. I've researched my RV for Dummies bible and looked around the online rv stores (we live in Germany, work with the US Army) but not sure if there are different sizes. We have a 2005 Fleetwood Tioga 31M with gas V10. We love RVing! Thanks for any help anyone can offer.
