I keep our motorhome plugged into shore power 90% of the time. After several days of temperatures in the 20s and below, I checked the coach and found frost on the outside of the batteries. Analog VOM showed about 11 volts. Still enough in the house batteries to fire up the generator. After running that for an hour (generator in front - batteries in back) no more frost on the batteries. I have a Progressive Dynamics 9260 Charger/Converter with intellicharge.
We are on our second motorhome and second extended maintenance program. The first one we took out on a six year old used motorhome. It was Good Sam Gold plan and I got more out of it than I paid in. I now have a six year XTRA-RIDE PLATINUM plan for our 2009 Destination. Not the least expensive by any means, but very good, complete coverage and extremely easy to deal with. It also gives us some peace of mind.
Our experience - YMMV
A couple years ago, my wife and I had a 10 year old motorhome. Retirement was still eight years off. We decided to purchase a new motorhome, with a good interest rate and have it half paid for by the time we retired. Stick and brick will be paid for by then so just have the motorhome payment. I am a local government employee with a defined benefit retirement. does give me some peace of mind knowing how much I should get each month in retirement.
Just our decision - YMMV
I use a 311 receiver in mine. I have the main TV connected to the receiver by RCA Cable, and the Coax output connected to the distribution box. I did find that the output of the Sat receiver was connected to the Auxilary port of the distribution box and not the Sat port. Set your other TV (s) to channel 3 or 4 and you should bet your Sat signal. All TVs in my coach must watch the same Sat channel as it is a single receiver.
