I don't remember the tongue scale, the hubby ordered it and comes wednesday. I'll keep you posted. The RV dealer gave us a husky WDH. It was very loud whenever we turned, you also can't backup with it on. We splurged on a blueox swaypro 550. Their customer service is top notch. You can call them or email them with any questions, any they will answer the phone nearly immediately, or respond to email within minutes.
Here's a collection of stuff I use that's required. I'm also using it as a list for replacements when needed.
Here's a list of things I might buy. I ended up buying the water hose from camping world since they are the only ones that I can find actually selling it. Hint: Get 2 50' hoses cause you never know. :\
I'm also thinking to purchase one of these:

This would allow me to drop a couple steramine tablets inline from the house water supply to clean the hose, fresh water tanks, water heater, city water inlet, etc. Steramine is super cheap and is very effective, and can even be used in food prep areas. Group camps will use this as a final soak/rinse to steralize everything before tossing on the dry rack/hang from mesh bag. You never know what may be lurking in your tanks after just a few refills.
