No, I haven’t noticed because I typically don’t like the layout and colors used in interior design of a Lance. But, I’d also say that unless you are taking the camper apart, you are going to get what you get. Based on the posts here for over a decade, most people seem to be able to get by in Winter/Summer no matter what brand they have.
Like Kayteg1, I’ve looked for cold spots. In my case, I added Reflectix to all of the clothes cabinets in the sleeping area and outside compartments. I also use Reflecitx in the skylights and vents, over the door glass and windows at night, and roll them up and store them in a bag during the day.
So, the advice would be buy the TC you like and look for ways to improve the insulation. I think that’s pretty universal to do no matter what brand you are talking about.
