solar panel strength durability

after posting on this forum have found to understand that i need about 120 watts of solar power to run my fridge. now my question what panel will hold up the rough roads and consistently moving on and of my camper trailer to follow the sun? have seen many claims that the unisolar panels are unbreakable, others say are panels are durable. look at www.tasmanenergy.com.au . these people also state the unisolar is more durable. the problem is a unisolar panel is a amorphoros panel and the others are moly crystaline. then again people say the unisolar panels outperform. [ not sure of conditions] the unisolar are larger and slightly more expensive. don't mind spending a few more dollars as it is a long term investment. do all panels have durable frames from which to mount? have seen many solar panel names, sizes and charts, prices.
it seems to me that many people are recommending the unisolar, why?
better profit margin? please give me your opinion as which panels you would buy? remember these panels will be mounted on my camper trailer boat rack. cheers, robert
