I purchased a used 2011 viking legend 2485sst last saturday. This is our first pup and i have a few questions for all of you. #1 i paid $6900 for it. did i get ripped off, nada is $12400? #2 i have a couple of black stains on the canvas (not vinyl), i tried some rv cleaner but it didnt work, any suggestions? #3 i have read quite a few posts about the positives of a BAL leveler, do you recommend? and finally #4 do any of you own a viking pup and have any suggestions or advise about concerns i should be aware of regarding this pup? thanks and i look forward to sharing our experiences with you.
