Just a suggestion.
Your first coach is a learning experience ie: In short order you will find things & designs that just do not work for your inside.(Do you have to convert sofa to bed each night? No counter space for food prep? Have to extend the slides just to use the toilet or to go to bed?)
Then there is the issues of drive abilities, will it stay in the lane or does every passing rig or side wind slap you around?
Your 1st coach should be an older used one that is what you think you want.
THEN make a list of what you like in the coach and what just ain't cutting it...After a year or so trust me things become clear as to what you can tolerate and what you cannot.
Then when you find your "perfect coach" You can buy it... because you are not saddled with years and years of payments for something that isn't what you really want & need.
Our first coach was a 10 year old 34' gas class A non slide..bought it cheep and used it for 5 years.... found that I did not like the gas engine,GM chassis,small water & holding tanks, 6 gal water heater that ran out of warm water 3 minutes into a shower (that was so small I threatened to hang soapy towels on the walls just so I could get into the shower and do the "twirl"), and steel spring ride shook everything to pieces AND NO BASEMENT STORAGE! or useable weight carrying/towing capacities ....
Then went looking and found our "forever coach" and paid cash for it..(wholesaled the old gas coach to the local "bottom feeder" rv lot)
Happy trails & good hunting
