Oliver Travel Trailers are manufactured in Hohenwald, Tennessee. It is one of several product lines produced at the Oliver Fiberglass Products plant. The trailer concept came from the Oliver family’s love of the outdoors and past experiences with other trailers. They wanted to build a unit that would last them and their families for years to come. Shell Construction: It takes four fiberglass shells to build the Oliver, two inner shells and two outer shells. The lower outer shell is first bolted to the aluminum frame. Some of the electrical wiring, all the plumbing lines, and the holding tanks are placed inside and the connections are made. Next the” inner bubble” is created by the bonding of the upper and lower inside shells. Inside the “bubble” created by these two shell are molded the seats, counters, cabinets and the recess for the floor tiles. At this time, all appropriate holes are cut into the “bubble”, the cabinets are finished off with their lighted interiors and doors, more electrical wiring is added and connected and the “inner bubble” is lowered inside the waiting lower outer shell. Plumbing connections are made in the kitchen and bath areas, wiring is connected to the lower areas and the upper outer shell is affixed to cap it all off.
