Our first time out in our TM!

We are now the proud owners of a 2005 3124KB! We picked it up last Saturday at Fountain, Colorado, Camping World....and for our first trick we got a flat tire on the TM only 1.5 miles from our home, Trinidad, CO. I know, I know, we should have checked the age of the tires. I read that tip on this wonderful and informative forum and somehow the 3 hours we spent at Camping World doing all kinds of set up and such, threw us off our learning curve...turned out the tires were from 2006! They might have looked good but they sure weren't. We bought 3 new Commodore E 15" (that's what it had on it) tires from Big 0 and I contacted Camping World about the problem...they were very kind and are going to split the cost of the tires (they are pretty expensive tires!) but we felt good to have new excellent tires. Then we load her up (lightly) and take off for our winter retreat from the snow, only we couldn't take off right away as our Durango battery was almost dead, seems the TM drains the car battery when plugged in (I didn't remember, but I did read about that here!) Jumped the battery, brought another battery with us, just in case and we are off! We get to a very nice KOA campground in New Mexico but it is dark and we set up the TM for the first time....that was almost out of a Lucy and Ricky Ricardo episode! 3 hours later we think we have it all set up correctly, furnace working, hot water heater working - that was a crack up as the dealer had winterized it with some sort of bypass tubing and we had to remove that and hook it back up correctly and the drain pipe was in the way.....but we got it, of course not without water everywhere, etc etc....then we cannot figure out why the lights won't work in the 1/2 of the trailer where the bathroom and king bed are...that took awhile to figure out that the bathroom wall has to be just right or the lights won't work. It was a learning experience but we had fun! We are now on night 2....we drove through rain and fog all day in New Mexico and Arizona and it is supposed to snow tonight - we are pretty toasty warm. We are having trouble closing the TM, but I read through the forums and will take some advice and make sure nothing is on the beds, that might have been the problem...I notice the main latches are not aligned with the little bars they catch on - this is on front and back...we may have some adjusting to do, but we also need to be sure we are level. We are loving the TM, it is different but very likeable - our two little Boston Terriers love sleeping on their doggie bed under the fold up table between the couches. I am sure we will have lots of questions as time goes on!
