Well .... floor plan may be king when you first look and buy .... but later on after owning it for awhile in a variety of situations you may wish that some other things had been more kingly at purchase time, such as:
1. Do the cabinet drawers have all steel slides and gravity locks?
2. Are the outside storage cabinet doors drop-shut, or do you have to bend down and push them shut?
3. Does it come with a spare tire and a lug nut wrench?
4. Are the outside mirrors heated and remotely adjustable?
5. Is the propane tank large enough to not need filling very often?
6. Is the fresh water tank large enough to not need filling constantly?
7. Is the black water tank large enough to not need emptying constantly?
8. Is the grey water tank large enough to not need emptying constantly?
9. Is the water pump easy to get at?
10. Does it have at least two coach batteries (best), or only one (not so versatile)?
11. Is the shower tall enough so all users can stand up in it fully?
12. Is the roof one piece fiberglass and crowned?
13. Is the built-in generator installed quiet enough and vibration-free enough to actually be usuable?
14. Are the bed mattresses pretty top notch for your comfort as delivered, or are you going to have to replace them shortly after purchase?
15. Does the fuel tank hold enough fuel for at least a 400 mile range?
16. If it has a propane refrigerator, does it have adjustable temperature settings?
17. If it has a propane refrigerator, does it's rear ventilation flue go straight up vertically (ideal) or does the flue have angles in it (not good)?
18. Are it's fresh, grey, black water tanks heated?
19. Does it have a rear ladder for access to the roof anywhere, anytime - especially if something needs checking or roadside repair up there during a trip?
20. Does it's air conditioner have distributed ceiling duct outlets (best), or just one central ceiling outlet (not so good)?
21. Does it's propane furnace have several outlets throughout the coach (including the bathroom), or just a few?
22. Is the bathroom ceiling ventilation fan's switch on the wall, or up high on the fan frame and thus hard to reach?
23. Are there plenty of 12V outlets throughout the coach interior?
24. Are there plenty of 120V outlets throughout the coack interior?
25. Is there a least one 120V outlet on an exterior coach wall?
26. Are there several outside storage bays, or just one big one -> thus wasting space behind coach lower walls that could have also contained small bays?
27. Are there at least two roof vents at each end of the coach, with one of them being reversible so as to provide versatile coach ventilation choices?
28. Does the cab passenger seat swivel to face the coach living area?
29. Is the exterior coach step automatic?
30. Did the dealer throw in a free installation of vent covers over all roof vents at purchase time?
31. Is there an emergency boost button in the cab for starting the engine with a dead starting battery?
Having the proper floor plan is important, but there are a whole bunch of other best-practices things - that if insisted upon when shopping - can sure make RV'ing more enjoyable and less work or less expensive later on in the ownership cycle!
