We have a 2304s Ultralite and love it. No floor or roof issues, feels very solid. We have a ladder. FYI the ultralites have features the minilites do not, such as enclosed underbelly, day/night shades in place of curtains, etc., etc. We looked at both models but the 2304s felt like a much larger trailer with the huge dinette slide compared to the 2503s minilite. The Murphy bed is super easy to use, the only issue being it is a bit high off the floor, so requires a bit of agility if you are short! The bathroom on both models is nice and big, but the 2304s has the toilet off to the side, so you are not looking at "the throne" if you want to leave the BR door open to get more light from the nice big back window! Just my 2 cents worth.
