Keystone – other models: the collective page of US travel trailers and fifth-wheels outside the named ranges, from Bullet and Outback to Montana and Cameo, unladen weights from 3,090 to 6,800 kg

This page gathers the Keystone travel trailers and fifth-wheel trailers the register could not assign to a named range. Keystone RV was founded in 1996 in Goshen, Indiana, and has belonged to Thor Industries, the largest recreational-vehicle group in the USA, since 2001. The ranges gathered here run from the lighter travel trailers of the Bullet and Outback families to the heavy fifth-wheels Montana and Cameo, towed via a kingpin on a pickup bed; suffixes such as High Country and Premier mark higher equipment lines within a given range.

The register lists here 13 versions with unladen weights from 3,090 to 6,800 kg, gross weights from 3,500 to 7,710 kg, lengths from 10,080 to 13,180 mm and widths from 2,500 to 2,550 mm.

With brands such as Montana and Cougar, Keystone is one of the best-selling fifth-wheel makers in North America; in Europe the vehicles reach the market mainly through importers and the used market, for long-distance travellers and campers with their own tow vehicle.

On a used purchase, moisture damage to roof and side walls, the condition of window and slide-out seals, the function of the levelling jacks and kingpin, axles and brakes, and, on the heavy fifth-wheels, the payload margin between unladen weight and gross weight all count; parts run through Keystone authorised workshops and the open RV trade.

What to check before buying

  • Search the frame and welds at the axle mounts — that is where cracks start.
  • Check the brakes and the last inspection in the papers.
  • Work the gross weight against the towing vehicle before buying.
  • Compare the chassis number with the papers.
  • Look at the floor, cover or body from the inside — rust does not show from outside.
