Altitude Changes

OK, started from Shreveport, 11 days ago headed to San Diego, winegard SD roadtrip, with Direct TV. Works all the way to San Diego on all stops, go to Camp Verde AZ, does not work, Santa Fe does not work, did not change anything, entered zip, checked all coordinates, Leave Santa Fe on way home, stop in Lubbock, ALL WORKS,
What is UP, will take all and any comments, is there something you do for 7000 ft?

I'd never considered altitude as a factor in aiming a satellite dish. Considering that geostationary satellites orbit at 22,223 miles above the earth (source: HowStuffWorks "How Satellites Work") I don't think that 7,000 feet, or just over a mile,would make any appreciable difference to the aiming angle. I recently did a trip from Oregon to N Carolina and my Tailgater automatic aiming antenna worked fine all the way. Sorry this doesn't give you an answer. Maybe someone with more brains than me will have a solution.

It seems to make a difference to me. I live just over 8000 feet elev in Colorado. At home, my Kingdome must be set on Zone 4 (Central West). If I travel east or south about 150 miles, and about 3000 feet lower in elevation, I need to change to Zone 5 (Middle/Center). It was very frustrating the first time. Now that I have figgered it out, it is the first thing I do when I get to a lower elev camp. \ken

Sleep Number Beds

As an aside, met someone who traveled from the East Coast to the Rockies in a brand new RV.

Salesman had not warned them of altitude effects on inflated objects -- long story short, their sleep number bed almost blew up.

I'm a bit surprised the type installed in a motorhome would have a problem. There were several posts on this some time ago. According to the manufacturer the ones put in motorhomes were supposed the have a relief valve to eliminate this problem.

Apparently the ones designed for motorhome use are more expensive than the ones designed for a stick house. Many people were taking delivery of a motorhome with the standard bed then purchasing a standard Sleep Number bed and installing it themselves. Some had the problem of over inflating and breaking the seams. Sleep Number wouldn't warranty them because they weren't meant for motorhome use.

IMHO that sounds like an explanation put forward by a salesperson as to why you need to buy the expensive "motorhome model" bed. The atmospheric pressure in Denver is ~.83 of what it is at sea level, a 17% decrease. Since the bed is designed to have users change the pressure in it and is supposed to be capable of having a 250-300 pound person sleeping on it, I find it hard to imagine that it can't handle a 17% decrease in the surrounding atmospheric pressure.

It sounds just like all the other over-priced RV stuff like RV-rated microwave ovens and TV's. If you think RV-rated stuff is over-priced, take a look at marine-rated equipment. Go buy the expensive version of the bed if that makes you feel more comfortable; IMHO there's a sucker born every minute.
