New / Old Owner

Hi Everyone.
I just picked up a 1989 27' so I guess I am not sure if I am a happy new owner or a old fool owner. I didn't give much for it and its not in bad shape from all I could see.
I did browse here a bit but do have a couple quick questions.
I was wondering about the upper and lower side seals. I see many people have just made there own.
1 - Are they available new from Trailmanor ?

The second thing I saw right away was that this unit is very low to the ground. Have any of you lifted one of these things by some sort of lift kit axle rework or change tire size ?

Well that's it for now I will take one thing at a time and try to put up some pics this weekend.
