I suggest going to a RV show to see lots of floorplans and makes and also watching some Y tube video's on how brands are built.
To add to this:
Brands and lines don't matter near as much as how the unit is maintained. You can buy a top brand / line, let it sit in the woods, and in a short time, it will be in poor condition. Or, you can buy an entry level, maintain it well, and it will last you a long time.
Most important items are floor plan, when, where, and how it will be used / maintained, and build specs that match your needs.
Examples:
Heated holding tanks is a marketing term.
Some manufacturers spray a thin coat of foam on the exposed tanks. Some, install electric heat pads (on the tanks and sewer dump lines), spray the tanks, add fiberglass insulation, route heat ducts near the tanks, and enclose the trailer underbelly. And, some with varying degrees of protection, in between. They all say "we have heated tanks".
Polar package, Cold weather package, Four season package, etc are also marketing terms.
Again, there are varying degrees of cold weather protection. Different wall, ceiling, and floor thickness. Different amounts or types of insulation.
The interior systems (refrigerator, stove, entertainment, heating and cooling, etc) are only made by a few subcontractors, and are pretty much standard for all brands / lines. Same applies to running gear and stabilizer jacks.
They all have their share of units built on Friday afternoon. And, they all will have minor issues after getting bounced down our bad roads.
