Hi, Cecil...
I predict you're going to make a lot of friends and be a very popular member based on your introduction, background, and druthers-in-life!
Since your RVing interests snared my attention this morning, I have a few starting thoughts.
First, if you've never been to the semi-annual TCA York (PA) meets...typically April and October each year...you might want to a) become a TCA member, and b) attend the York meets as well as those in your local TCA division throughout the rest of the year. The meets at York have LOTS of room and provisions for RV folks right on the fair grounds. And, if you're goal is to have an RV layout on board, you'll be sure to have a lot of after-hours attention/partying/help/questions/etc./etc..
Second, if I were you, to kick things off regarding your interest in an on-board RV layout, I'd start a new thread on the forum focusing on the RV itself...photos (inside and out), druthers for the layout (size, features/accessories/trains/etc, storage limitations, other riders/pets, blah, blah...IOW, something for us to 'chew' on. I'm sure we'll have questions/suggestions along the way. Like, are you towing?...car?...storage trailer?...or, averse to doing so in the future?
Wife and I and our 2 Goldens were RVers for about 10 years. In fact, since my wife is as much into the hobby as I, and our current focus is in the O3R end of the hobby, the semi-annual York meets were a huge reason for our 'hitting the road'. (Spending some time escaping Michigan winters travelling to Florida was the other enticement!!). Our last RV, a class A, had a nice electric drop-down single bed in the front driver/passenger area that was never used for sleeping, but BEGGED for a small layout. For this purpose I hung onto a modest collection of N-scale stuff from earlier years, but never took the time to build that layout! It was always a conversational dream, though. (Aging's effect on eyesight and manual dexterity were more encouraging to forego future N-scale thoughts/efforts, and focus on O3R! Nonetheless, the possibilities of bringing the hobby along with the transportation was part of the RV fun...in thoughts/dreams, anyway!!!)
Re your request..."Be gentle". I think most of us are...or we'd like to think we are!!! But, hang tough!...A lot of us are also of the 'geezer' class (4 months to octogenarianship, here), and, well, 'we' have our moments...exacerbated by elections, stupidity, impatience, warm fruity beer, menus using foreign languages to describe boring food, ...etc., etc., blah, blah. IOW, reasons to think about happier days...and looking forward to 'going home!'
