Giant Recreation World Sold us a travel trailer that is a piece of junk! Melbourne Florida

Giant Recreation World located in Melbourne, Fl. Sold my husband and me a 30' Forest a River travel trailer that has caused a nothing but problems. It is a 2016 but appeared to have a little wear on it when we bought it off the showroom floor. We figured this was just from people looking at it as they shopped. We were told we were getting a great bargain but have learned since that great bargains come at a price! The first problem was that we were told that our Nissan truck would be able to haul the trailer because it was so light. Wrong!! After we purchased it, we realized we needed a bigger truck so we shelled out a lot of money for a heavy duty truck to haul the trailer. Next came all the material problems with the trailer: parts falling off inside and out, stabilizers that don't work, water backing up in the tub and sinks, a toilet seal that mysteriously vanished, closet and cabinet doors that came off their hinges, a. Furnace that pooped out when it was very cold outside ( we had to purchase a portable heater to keep warm), threads coming loose on all the furniture, wobbly sink faucets, shower trim that came off, mattress that is slowly sinking into the cheap piece of wood it sits on, toilet paper holder that popped off, straps that hold chairs while traveling coming loose from the wall...I could go on and on! This is a piece of junk! We are so upset because we have dreamed of traveling and when all of this stuff started happening, my husband had to try to fix it himself. We are up in Ga. Now and have no way of rectifying any of these problems until we get back home in three weeks. We are very Leary of having GRW even touch our trailer for fear they will do more harm than good! What can be done? We are seniors on a fixed income and are not rich.
