We desperately need some external thermal screens for our MH which is a 1999 transit base. I have been looking for a while....need them before Christmas as we're off to Disney Anyway, no one here is selling any so I've been looking around. I don't want to spend too much, probably no more the £90. I've seen some branded Nova Leisure, and also silver products. Is one of these brands better than the other, or are there any others for around this price I should be looking at? The genuine silver screens seem a bit too expensive brand new.
