I am not aware of discontinuation of the A127TH. I'm certainly glad I got one and I anticipate enjoying it a great deal.
My primary TV is my venerable '02 F350 SRW CC longbed diesel 4WD. It's got the standard 5,000 lb receiver hitch and RV wiring system, so it's pretty much "plug and play". I use a 6" drop-down drawbar to keep the utility trailers I use level and I believe I'll want the same drop for the Rockwood. I just need to get a wireless brake controller. I'm already pondering pulling the mud-terrain tires off of the camper and replacing them with a pair of high-rated Marathons or other trailer tires. I frankly think the M/T tires on the camper are a bit gimmicky, or at least are of little if any use to me. With the TH platform adding to the length, it's a bit much to think of knarly off-road towing uses. A shorter camper and a lighter, shorter truck--sure, but I'll be pushing 40' nose-to-tail and around 13,000 lbs on the hoof, so unless I want to chance burying the rig in mud or sand, I don't anticipate any true off-road use. Besides, I want a pair of mud/snow tires for the back of the 2WD Mazda, anyway, so there we are.
We focused our search on pop-ups in the 2,000-2,500 lbs dry weight range in order to have the option of towing with my wife's Chevy Equinox (V6 with 3,500 lb tow rating), my daily driver Mazda pickup (V-6, 2,500 lb tow rating), or a close friend's 2006 Tacoma Quad-Cab (5,000 lb tow rating(?)). I will likely never actually tow any real distance with the Mazda or the Equinox, but we wanted the option of using one or the other for very short trips to the lakes or State Parks in this part of North Carolina. There are about a dozen CGs within 50-60 miles of our Raleigh home.
I'm looking forward to chiming in with a trip report in a couple of weeks.
Newbie to modern-era small RV camping, but grew up in the 1960s with a Cox tent camper w/ parents and 3 sisters. Yes, a little tight in there.
