Congratulations on your new Sundance! How exciting!!!
Whatever filtration system you pick, make sure you look at the flow rate of the filter. There are a lot of inexpensive filters out there, but they limit your flow of water into your coach so bad that it is hard to take a shower or wash dishes, as there is not enough water flow to keep up. We use the
Hydro Life RV/Marine inline filtration kit which provides 2.5 gallons per minute of water flow, but yet has great filtration qualities. I could not believe the difference when we switched to this from some of the cheaper in line filters.
Another option if you are handy is to install an inline filter for your kitchen sink or an
entire drinking water filtration kit so you are only filtering the water going to your kitchen sink or in the later case, your drinking water only. In the long run this is a cheaper method as the filters last longer because they get used less. The trade off is, that the water going to the rest of the coach is not filtered and therefore can often have some particles and bacteria that might have otherwise been filtered out.
