I did a light conversion to my Hercules 14x7. Insulated walls, ceiling; ran electric with breaker box for outlets, lights; added roof AC, Fantastic Fan, propane heater with t'stat; windows. No plumbing; fashioned a sink from a SS mixing bowl with catch bucket under. Left it bare inside so can still use to haul motorcycles, etc. Plastic shelving for microwave, coffee maker, plastic drawer stacks. Use cots, small table and chairs for furniture.
Has been great. Perfect for dry camping, hunting. Recently upgraded to the MicroLite, but it will stay at the lake so we'll still use the 'tramper'.
