What year are you looking at? As for warranty, get the dealer to include an Xtra-ride warranty.
The Cameo was below the Carri-lite in amenities, but built with the same structure. I am not sure about the Cabo.
One issue that the Carriage RV had was slide motors and gears, especially on the larger slide for mechanical units.
Another issue was the use of E rated tires at or over their load limits. My preference is to go to 17.5" wheels with H rated tires. The other option is 16" wheels and a G rated tire. I would not accept a Carriage with E rated tires.
There has also been a problem with the suspension and the plastic bushings failing. This is easy to fixed with a wet-bolt kit which includes heavier shackles, bronze bushings and bolts drilled with grease fittings.
Carriage built a much better than average trailer and has a loyal following. The Carriage folks moved over to LifeStyle Luxury RV and is continuing with the design with corrections for the few problems they had.
There is an active Carriage group on Yahoo and also at
Carriage 5th Wheel Owners Forum - Index
LifeStyle is offering some limited support for the group.
I would not have any issues with buying a carriage product.
