Define ''All Season'' campers please

In theory, you "shouldn't" have to make additional improvements, but in practice, you probably do. Or at least I think every camper tends to have a weak spot or two, weather it be a single line that runs too close to the side, or a pocket somewhere that doesn't get any real air-flow, or a wide open gap somewhere to the outside. It only takes one little mistake in assembly to cause a problem. I've been cutting into my camper all over the place for the last 4-5 years to be able to see and access everything as much as possible, and be able to correct things, or at least access things in the case of a problem. I listed my basement work and HVAC/Insulation changes as the most important "mod" I've done on the camper and still feel that way. Not too "sexy" a mod, but effective? You bet! If you are going to be serious about winter camping in a large TC I think it is a very very important step to take.
