The compact Jackpot is a low-budget alternative, suitable for three persons. It has a double bed plus a single hammock-stretcher bed. It also has a small kitchen with a portable stove and fridge. In New Zealand you can, on request, get a Porta Potti toilet with the Jackpot so it can be used on Freedom Campsites.
No childseats can be fitted in the Jackpot but it does take one boosterseat on the front passenger seat.
