May I also add some things to be aware of on the first motorhome?
Lots of small points are not as we might assume them to be!
Batteries and what to expect is a big one to trip folks as labels and names may not mean what they seem and keeping batteries in good shape is certain to be a learning experience for an RV as it is so much different than the cars most are used to using.
If a car is driven once a week or more, it keeps the battery from going down. But in an RV, there are almost always small drains working to run the batteries down and if we store the RV for a few weeks or months, it may kill the batteries and that finally requires replacing them if done too often!
A big mystery is the "battery cutoff" switches! So it can come around to you wanting to store the RV, so you want to keep the batteries in good shape, so you have it plugged in to let the normal charging from the converter keep the batteries good. Seems logical?
So, since you are not using anything in the RV, while stored, why not turn the battery disconnect switch off??
Problem is that the converter only charges the coach batteries if we don't do some special move to keep the chassis battery also charged! But the real killer is that the battery disconnect switch DOES disconnect the battery from MOST of the drains but also from the charging! Safety items like CO and propane detectors on the coach battery and radio presets or door locks, etc. on the chassis can still kill the batteries!
Recommend almost neurotic watching the voltage for the first time until getting the details well in mind!
