J-Steel sofa replacement

[McKenzieFamJam]

We recently purchased a used 2010 Jayco 29BHS Jay Flight TT and the J-Steel Sofa has a large tear in the upholstery. We want to replace the sofa and just wondering if anyone on here would know where we could purchase a replacement sofa? We live in Alberta so it would have to be either within Alberta or online with shipping within Canada. Also, does anyone know if this is a fairly easy Do if yourself project or would it be best to have the sofa professional installed. Sorry these may be simple questions but our last trailer was purchased new from a dealer and did not require any "work" while we owned it so this is all new for us.
Thanks!!

Why not have it reupholstered? These rigs are kind of designed around the furniture so it maybe hard to find a sofa that fits the same.
