First let me admit I'm one of those on the RV forums who really rants against his Cyclone. We've had ours just over two years. The first year, it seemed like something would break every single trip.
We'd only had it two months when the brakes failed. Our dealer tried everything but to no avail. We tried to get help from Heartland but they wanted nothing to do with us. It was "Dexter made the axles, deal with Dexter." I paid $55,000 for a camper and after two months the brakes fail. The manufacturer of the camper doesn't care? Wow. Finally we did contact Dexter and after much research, Dexter upgraded (for free) the brakes to a heavier unit and they were great. Excellent customer service from Dexter.
In addition to the first year with the brakes: Three failed water pumps, two AC repairs, wallpaper peeling, door trim popping off in numerous places, doors not lined up with their jambs, black tank flush flooded the storage compartment the first time we used it, winterization hose installed incorrectly and couldn't be pulled out, right side plastic fender flew off on the interstate because the screws backed out and the plastic cracked, and the motor for the rear stabilizer locked up.
After one year, the dreaded TowMax tires did their usual thing. "Boom" on the right front tire. Tire dealer said "tread separation". $1400 to replace 15 month old tires. $700 in fender damage from the tread beating the side. When I called Heartland, the tech tried his absolute best to convince me the TowMax tires were "the best tire they've ever used". I reminded him of the numerous tire failures on the Heartland forum but he claimed he wasn't aware of them. Hmmm?
Some of these things are not made by Heartland. I understand that. But as many problems as we had (especially after the brakes issue), customer service from Heartland was pitiful whenever we needed assistance.

Now back to your original post. The roof height concern for the vast majority of toy haulers and golf carts is only for ones with a loft. That's what hangs down so low, it gets really close to the roof.
Raptor, Fuzion, Voltage, XLR, Inferno, and Seismic are nice models to consider.
As for the three ACs. I believe they are all only to run two at a time. Not enough power to run three. The Cyclones with three ACs have a transfer switch to allow power to flow to the bedroom or the garage AC.
Golf Carts: Look craigslist as well as dealers in your area, EZ-GO and Club Car are the norm. Club Car has an aluminum frame which means no rust. Yamahas are not quite as popular at the campgrounds. They are in general more difficult to work on and upgrade.
Is it worth it? For us, we couldn't imagine going to the Fort, Ocean Lakes, or Willow Tree without our cart. Its a whole other experience.
Browse through this thread. I started it under my old screen name years ago. That's our first cart back in 2008.
