I have a 13 Laredo 240MK. We purchased new at Buffalo RV online. Got it for about 19500 plus tax, license etc. We have trailed it from NY to FL. twice now. Had 2 minor issues which I have fixed myself. Have not been back to the dealer since I brought it home. Do not know about any frame issues. Hit a speed bump at about 40 that I did not see until too late last year that really bounced the truck and trailer but did not hurt anything. Seems pretty durable to me.
We spend about 3 months in FL with it and plan to take it to Acadia National Park in Maine this fall. The floorplan works well for the 2 of us and our small dog. The Laredo has some very nice features over our previous TT. The 50" shower is especially nice along with 8 cu. ft. refrigerator, fiberglass front nose cap, residential queen bed, 15" wheels, 50 amp. electric, higher ceiling, extra wardrobe closet, bath linen closet,many awning windows (they can stay open in a light rain) and the 32" TV on swing arm.
We felt it was a good value for that price and it tows nicely.
