RV review: Wildwood Heritage Glen ROOST43—The largest RV I’ve ever seen!

Today’s RV review might be of the largest RV I’ve ever seen—the 2025 Wildwood Heritage Glen ROOST43. This is a category-busting model that does fit in with some other classifications of RV. But it’s so different, in some ways, that it’s absolutely worth a look. 

What you have here is the marriage between a destination trailer and a fifth wheel, resulting in a floor plan that has more than 500 square feet of interior space. This is a huge, heavy beast with three slides, all of which have slide topper awnings as standard. 

In fact, a lot of things that some might consider reasonable options are standard in this trailer. 

Start at the road with the Wildwood Heritage Glen ROOST43

Normally I might not be thrilled with off-brand tires and a simple leaf spring suspension. But this trailer is very likely going to get towed somewhere and then just stay there for years and years. In fact, I would be surprised if many of the owners of these trailers ever even tow them themselves. 

When I worked at the dealership, we would often tow the largest trailers to someone’s property, where the trailer would live out its life. With a gross weight of 18,780 pounds and a hitch weight of about 3,480 pounds, you’re not going to tow this with the average pick ‘em up truck. 

I do like a lot of how this was built with the idea that I’ve only seen the prototype. For example, the underbelly is fully enclosed and the gate valves for the holding tanks are within that enclosed underbelly. There are also 12-volt tank heaters. 

Unlike a lot of destination trailers, this features an on-demand water heater. That makes sense, especially in light of the fact that this trailer comes with a washer and dryer as standard equipment. 

Unusual features in the Wildwood Heritage Glen ROOST43

While this is a fifth wheel in configuration, there are a lot of things that are done unusually. Those include the wet bay, which takes the entire space behind the road-side compartment door. To compensate for this, there’s a slide-out tray on the camp side that’s rated to hold up to 800 pounds, similar to what you’d find in some motorhomes. 

The only entry door into this RV is a sliding glass door. That makes sense in that many, many of these are going to be permanently placed and someone’s going to build a patio deck. In fact, this is how the prototype was displayed—with a patio deck built alongside it. 

The roof of this fifth wheel is a single height and is angled just slightly to the off-camp side. There are three air conditioners up here but, otherwise, it’s pretty flat. If you did have a property where you wanted to put a bunch of solar, you could certainly put a bunch of solar up here.

Main living space in the Wildwood Heritage Glen ROOST43

Quite honestly, I think this rig is nicer than my house. Walking in, there’s a huge feel with high ceilings in the main kitchen/dining area. The visual centerpiece here is an island that extends out with five bar-height seats. The sink in the island incorporates one of those new sink designs that has multiple bowls that slot into it plus a glass washer. 

Storage and cabinet space are reasonably plentiful with hutches and cabinets. 

Since you could use the bar as seating or prep space, you could do some serious cooking here. That’s especially true with the large 20-cubic-foot, 12-volt fridge and enormous (by RV standards) propane oven with a four-burner propane cooktop. 

Toward the back of this space is an L-shaped couch. Wildwood even includes a coffee table, which is pretty unusual. 

Across from that couch is a huge 65-inch TV with an electric fireplace below that. 

A real visual centerpiece, even though it’s at the back of the space, is a spiral staircase up to the loft that’s above the living room. Unlike in some RVs that have lofts, the ceiling in the living room still offers plenty of height. 

Main bathroom in the Wildwood Heritage Glen ROOST43

The bathroom deserves its own story here, as it is huuuuuuge and is right off the main living space. Over on the camp side are a washer and dryer. Above those is a drop-down shelf for folding laundry or whatever. 

There’s a vanity here with a vessel-style sink. There’s actually decent counter space here. And there’s a very large shower with a drop-down teak seat. The toilet also has plenty of space around it. There’s a door next to the toilet that slides open to reveal more storage. If your definition of a place is fancy based on the bathroom, you have a fancy place here. 

Lofty expectations

The bathroom is under one of two lofts in this trailer. The one above the bathroom is fully padded so it could be a bed for humans or pets, although I don’t think many pets will navigate their way up here. I could see this space being used for storage, but whatever. 

There’s another loft above the living room that has two mattress pads and a half dozen totes for storage along with a short closet. This would really be a cool place for kids but adults would have difficulty sitting upright in this space. 

However, there’s sort of a fancy grate over the front of the back loft that enables the occupants to look down on the kitchen and observe the goings on there. Should the occupants of the back loft happen to have something like a Nerf gun, they could get into quite a lot of trouble from this perch. 

I’m sure the family chef wouldn’t want Nerf bullets in the chili, although you could arrange some sort of spice delivery system where the cook could say, “More salt, please,” and the shooter from their position could so bless the meal. 

Front bedroom in the Wildwood Heritage Glen ROOST43

I mentioned the spiral staircase at the back of the main living space in this trailer. Also, there’s sort of a half spiral staircase at the front of the space. That leads you to the loft above the bathroom but then, down the hall, you’ll find the main bedroom.

There is a step down into that bedroom, which could be a tripping hazard if you don’t remember it’s there at night.

Fortunately, this is another very large space with a proper king-sized bed. The front of the trailer has windows in typical destination trailer fashion. A large counter is stretched across this whole width. There’s a spot in the counter where you could sit. There’s even a round ottoman so you could sit here and lord over the other folks in the campground or wherever you are.

You could have a fun game of adopting a farcical French accent and then launching bovines at the silly English knights who come looking for the holy grail. Ahem.

On the camp side are some closets along with a TV. There is a half-bath up here, so that tripping hazard is minimized as you won’t be stumbling to that huge downstairs bathroom in the middle of the night. That is, unless you get some hankering to do laundry or something.

Conclusions about the Wildwood Heritage Glen ROOST43

If I had some beautiful mountain property or something along a lake or whatever and needed a cabin or house there lickety-split, this would be a fantastic way to accomplish that, assuming local ordinances allow me to use this in such a manner. 

This is a really beautiful fifth wheel that’s truly unique. Aside from that step down into the bedroom, I find it difficult to find fault with this rig in the right context. I wouldn’t want to venture around the U.S. with this thing, but I could see it serving me well as a destination trailer. 

I also think they struck the right balance between RV-focused pieces (12-volt fridge, on-demand water heater) and destination trailer design. 

Certainly, not everybody could have a place for something of this size but, given the right context, I like it.
