I don't have a "phobia" about them, but, I don't think I'll ever own one. In a MH of some sort maybe; they have a suspension system to take the jolts out of the rear, but, trailers are lot less forgiving on stuff in the rear.
Look at the physics; the front is supported, cushioned, and reigned in by the attachment point to the TV. The middle is directly over the axles and cushioned by the limited suspension found there. The rear? Nothing. Just like a roller coaster; if you want the wildest ride possible, sit in the back.
The rear end takes a lot more punishment than anywhere else in the trailer. All of the stuff in my cabinets remain in place, no matter what the road conditions are except for the stuff in the rear most cabinets.
Over a lot of years, we've learned what to put in those rear most cabinets and none of it is breakable
I can leave stuff sit out on any of the counter tops in the rest of the trailer and usually find them still sitting there, except for the end table in the rear; I have a lamp there that is attached by 4 3M Command picture hanging strips to keep it from moving and if I forget to pick up a coaster before we leave, it will be on the floor when we stop. I personally, don't want to even think about the possible consequences to our dinnerware, utensils, pots and pans, pantry items, etc. along with the myriad of hardware connections; plumbing inlets and drains, LP couplings, stuff in the refrigerator, etc. Granted, 98% of the time nothing would move or go wrong provided you packed everything back there with possible movement in mind.
We also prefer the living area to be in the back. If there is a view, it will be back there and not each side. If the living area was in the middle, we'd have a great view of the rig on either side of us and unless the kitchen area (in the rear) had its own door, that is a long way to go for a cold one. With the kitchen in the middle, and ours in particular, the refrigerator is right next to the door.
A friend of ours has a TT with a bathroom in the back... He has to use Velcro straps to keep the medicine cabinet and vanity cabinet doors strapped shut, and when you open the medicine cabinet after stopping, you best be prepared to pick most of the stuff out of the sink and replace it on the shelves. He had a lot of problems with the drain pipe fitting coming loose and leaking until I strapped it tight with self-fusing tape. There is still a small leak in the shower's drain, but, they don't use it very often and we just haven't gotten around to pulling the chloroplast in order to access it for repair. He has a second door in that rear bathroom to the outside; we've had to adjust it several times as it shifts on its mounting and binds. His kitchen is in a slide and the sink is closest to the rear, right next to the bathroom wall. He has to remember to take the Pur water filter off the faucet because it will pop off and bang around in the sink if he doesn't and he has had problems with the drains leaking under the sink (again, some judicious use of self-fusing tape has that fixed).
Just some of the reasons I
don't want one; no "phobia" about it, I just don't want one. Lots of people like the rear kitchens and lots of people have them and they either don't have the above problems or they've figured out ways to cope. If that is the design that you like - go for it, that's why they still make them, for folks that like them and none of the reasons that I
don't want one are insurmountable, I just don't want to deal with them.
