RV review: 2025 Alliance RV Delta Ultra Lite ML206 preview—First look

Today’s RV review is of the new 2025 Alliance RV Delta Ultra Lite ML206 travel trailer. This is a new series from Alliance RV currently available in two floor plans and is an example of the decontenting that we’ve been talking about lately. But, as in many cases, that’s not a bad thing. 

I got to tour the Alliance RV factory last week and see how some of their products are made. Touring any RV factory is eye-opening if you haven’t done so in the past. The difference between the Alliance operation and many others I’ve seen was substantial… and that’s an understatement. 

Starting at the bottom of the Alliance RV Delta Ultra Lite ML206

The Ultra Lite series starts with Goodyear Endurance tires, which are my personal favorite. But you’re getting a traditional leaf spring suspension, which is the first obvious cut the company has made. 

Interestingly, Alliance RV still features an enclosed underbelly, and the plumbing features a shutoff for each fixture. There are three spray ports on the outside of this trailer. They are really unique in that there are hot and cold knobs in the wet bay which affect the water temperature in all three of the outside spray ports.  

The company also intentionally wires these trailers with consistent colors of wiring—which makes a difference down the road. 

Something that’s nifty about these is that there’s a switch for the awning in the front pass-through storage, which I really like.

What’s inside the Alliance RV Delta Ultra Lite ML206

If you’re shopping for RVs and find a floor plan that works for you, shop other brands. This floor plan is the same as the trailer I currently have, but there are some significant differences in the execution. 

The kitchen counter in my trailer, which has the same floor plan, is pretty comparable. But the manufacturer of my rig has an indent and then a flip-up counter extension. This also has a flip-up counter extension in the same place but it’s double the width and is flush with the rest of the counter when it’s flipped up. It’s a neat design. 

There’s also a little cubby below this spot so you could pull a stool up to this counter area and use it either for a desk, with the 12-volt TV above even being a monitor, or for more prep space. Who doesn’t need more prep space? 

But this has the worthless 17” (vertical) oven, whereas my rig has the larger 21” oven.

This also has a larger single-bowl sink. Alliance is unique in how they offset the drain on their sinks so they can take advantage of that space to put stuff underneath. Like drawer space. Or a cabinet that will hold a trash can. 

Drawers inside pantry cabinet

Something I really like that Alliance did in the pantry opposite the kitchen counter is putting drawers inside the pantry cabinet.

That slide is a bit taller than average, too. Yes, I have hit my noggin on a light fixture in my slide room. 

Another thing I like is the adjustable shelves in the pantry/closet by the entryway door. Alliance tends to be good with their cabinet ideas. 

The bathroom is comparable to the one I have in my own trailer. Well, except this has one of those worthless four-inch vent fans. But this does have flip-down towel hooks on the door which we liked so much it got us to go shopping for them.

Something good about this floor plan in general is that there is a tremendous amount of interior storage. I mentioned the pantry by the door, another in the slide with those drawers inside, and a third decent-sized closet in the bathroom. 

In fact, we’ve been looking at some slightly larger trailers and they don’t have the interior storage that this thing does.

Boondocking and travel access in the Alliance RV Delta Ultra Lite ML206

Apparently, there were some thoughts to dropping the solar panel on the Ultra Lite series, but that didn’t happen. So this still has a 200-watt solar panel standard with a 40-amp MPPT charge controller. This truly is ready for more solar, if that makes sense. 

We can use our trailer with the slide in, and that’s true here, as well. 

Visiting an Alliance RV factory

Alliance RV has the benefit of having all-new factories and a culture of treating the teams well. I was surprised with some of the ways the company has worked to minimize the strain on the employees. For example, there is a big vacuum mounting tool for the front nose caps so the employees don’t have to lift them. 

There are a number of overhead cranes so that employees don’t have to lift larger and bulkier items. These plants are also climate-controlled, which is another unusual thing in the RV industry. 

These factories are enormous and are the envy of a lot of others in the RV manufacturing space. I also think Joe Mehl, the Vice President of Marketing of Alliance RV, is probably doing one of the best jobs out there with his videos and the company’s website. 

Something else I liked was this huge vibrating plate mechanism in the company’s quality assurance area. This plate literally vibrates the daylights out of the trailer to make sure nothing is attached poorly. It simulates something like 24 miles of driving on a rough road, and every single trailer is subjected to this machine. 

Conclusions

There are a few things I would change about this, starting with the worthless 17” (vertical) oven and four-inch vent fan. It’s a bummer to see these in a brand with a premium reputation. There are lesser brands who have either ditched the oven altogether or just put a convection microwave in instead. Cherokee, which is an entry-level brand from Forest River, uses the high-performance vent fan in their budget-priced offerings, so it can be done. 

So, do I like my own trailer better or this design with some pretty nifty aspects of it? Well, I do think my own trailer is better made. That might be why I continue to buy Rockwood products and have developed a great working relationship with that company. 

But also remember this is specifically designed to be lighter and more affordable than a traditional Alliance RV travel trailer. And they did that with some neat features and design aspects.
