First, don't listen to those who say they will shake apart. That is coming from people who don't own one.
The Opus is great and the top of the line for offroad capability and luxury. But, can you afford it? $30k is the intro level. If you don't mind the price tag, get one!
I for one am having the time of my life in my family hand-me-down 1986 Coleman Plantation Tara. My father bought it when it was a year or 2 old and it's seen probably over a million miles, about 20% offroad. Beaches, desert, forests, etc. Not one piece has come apart due to offroading. Only kids abusing things. It still has the original Dexter Torflex 2500lb axle with I believe a 10 degree up angle. That put it super low to the ground and scraped driveways and ditches everywhere it went. When I got it from my father, I immediately welded on a 5" block kit. It no longer scrapes driveways, but I have to admit the axle has seen its days. Hopefully this week I'll be finalizing my decision on either the $800 Timbren axle-less or the $1750 Cruisemaster XT trailing arm design.
My family of 5 would never sleep on a RTT and Texas summers are brutal. I bring along a Predator 3500 to run the rooftop AC.
To put the whole "it'll shake itself apart" nonsense, I'll go in a little depth with a history lesson. The old Coleman campers from the 80's and 90's were the cream of the crop! They were very well built with box framing, metal stud interior, and heavier paneling. They truly don't make them like they use to. New campers are built cheaper, lighter, and fall apart before they hit the showroom. The exceptions are the Opus and purpose built trailers with the heavy price tag. In my opinion, save yourself some money and buy a well taken care of used pop-up for around $5k and modify it to suite your needs as I have. They really have not changed much at all. I've only added USB receptacles and a Renogy solar system to keep up with the kids' tablet and phone needs at night. After the suspension upgrade, not sure what else you can do? Like I said, not much has changed in 30+ years.
BTW, first post. Glad to be here.
