I'm scratching my head over the lack of roof vents on the 262RB. The other manufacturers offering competing models all have them and they are extremely important for air circulation, especially on warm days when when you can't use your AC due to lack of shore power or would rather just have fresh air. Being able to have roof vents cracked open is also important to keep air flowing in the trailer during storage and prevent condensation buildup when using the trailer. Does anyone have any thoughts on Alliance's rationale for omitting roof vents given the clear advantages of have them?
