Considering purchasing RV for permanent living

Welcome any suggestions/ advice regarding purchasing a travel trailer or 5th Wheel, purchasing a lot (with zoning) and docking my RV for full time living. Will sell house that is too much space and maintenance for me- retired in my mid 60's. Visited several RV dealers to day to get a feel for money and space and the guts to do this. Already learned not to sell house first but to purchase the RV then sell and move due to red tape and "full time" residency. Hoping to eliminate debt as my current too large home is starving for attention, so was already a learning experience. Very nervous about making this transition and not sure why. Lots of "stuff" to deal with, and new lifestyle. Not much into travel any more; don't have vehicle for towing anyway. Would rather purchase a brand new trailer but realize the depreciation etc but concerned about buying someone's problems. Just me and my 2 Russianblues.
Thoughts are welcomed.
EDIT:Edit: my plan explained: live in rv temporarily for couple of years on lot to build cabin later. Full time residency meaning docking it for a few years to build cabin later on same lot. "Full time r v " . Not wanting to establish other permanent residency in mobile park, fees associated with condo, pricing, etc though appreciate the advice. Would not be gaining anything. Have nice home - just need less space so transition is to get to a new cabin- 1000 sq ft. RV would be purchased as temporary living space to get there and assumed "full time rving" would be the same. What I am hearing is a travel trailer and 5th wheel isn't really full time status. and need to upgrade? Full time rving explained? Thanks.
