We upgraded to a Keystone Laredo 2004 to match our 3/4 ton ford truck and it has been great for week long stays, but reading this forum and hoping to snowbird or more what  troubles will come with using this camper full time?

Most full timers do not have 4 season RVs so you are not alone. Below about 20 degrees and above 100 to 105 most RVs have issues. Cold is the worst problem since ice causes great damage. You can have frozen pipes even with the heat on, which caused friends who attempted to winter in Dayton, Ohio to head south in a very nice 5th wheel. We have a well insulated RV and above about 103 degrees the air conditioning slowly loses ground. We have been down to 13 degrees in high altitudes but it warmed up during the day so our water and waste system did not have sustained below freezing to deal with.

As long as you do not head to extreme areas of cold or heat, you will be fine.

You will be o.k. Just keep up with your preventive maintinance.My opinion and my opinion only I THINK there are more people full timing in snow bird and a few vacation rated rigs than in the expensive. Bill Joyce said it best in his post.

Hmm, to me 'snowbird' means you stay where it's warm! If you do that, you should have minimal problems and you'll be in good company. As long as you can maintain electric hookups, small electric heaters are lifesavers for comfort! Our RV has a 4-season package with higher R values for the ceiling and walls - the heat and a/c are ducted into a portion of the basement. The slides, however, do not have any extra insulation and the electric heaters were necessary to keep us comfortable in 30 F temps and below. We saw many vacation type RV's in our winter travels (with this past winter being a pretty tough one in normally warmer climates). Everyone had to take precautions with their water systems.
