Newalaskan, Welcome!!! We have had an M-22 pulled by a Buick Enclave V6. I installed a Reese sway control WDH, a Prodigy brake controller, and an external transmission cooler. The Enclave has a towing package which provides for higher transmission shift points when towing. Loaded, it is a the top end of the towing capacity. We camp on average, for one week a month, so about five weeks a year in our climate. We mostly stay at provincial camp grounds within a 6 hour drive of our residence.
Before deciding whether the Ridgeline is appropriate, you must decide what style of camping you will be doing for the next couple of years, or however long you plan to keep the Ridgeline. If your camping will be similar to ours, then in my opinion the Ridgeline will be perfect. If you plan to do long distances, or pulling through the mountains, then a tow vehicle with a larger engine and higher weight limits would be more appropriate. We are careful in watching the weight of items that we carry in the trailer to keep the weight within capacity, but with us only camping a week at a time, this is not an issue. If you are planning a 6 week trip across the continent, you will drive yourself nuts watching your weight. In summary, shorter distances for a week or two at a time: Ridgeline is perfect. Long distances with hills for weeks at time: V8 with a higher weight limit.
Now some thoughts on the trailer. I have not seen an M-23, but it appears to be similar to our M-22 in several respects. One of the main reasons we chose the M-22 is that the dining seating area converts to a bed long enough to fit an adult, or two with a tight fit. The bunks are not large and very narrow to comfortably sleep an adult, so I think they would be appropriate for children. We use the bunks for storage. We really, really, REALLY like the slide out, as it opens up the interior immensely. I like the tub/shower in the M-23 better than the corner shower in the M-22. The corner shower is a "shower of last resort", and like the bunks, is better suited to children. We usually use the camp ground showers with lots of space and tons of hot water. In summary: Bunks are great for kids. Dinette sleeps adults. Tub/shower is better in the M-23. If you are travelling with more than two adults and two children, you are really, really, REALLY going to appreciate the slide out in the M-22. And it is only 100 lbs. heavier. Take a close look at the M-22 to see if it is more appropriate.
All that being said, we have found the quality of the Edge to be very acceptable with no major issues. Make sure that you deal with a reputable dealer. I would place the quality of the dealer as high or higher than the brand of trailer. If you have major problems, you need a good dealer far more than you need the trailer!!!
Best of luck.
