Those plastic slide in fishing shacks?

[bat119]

Has anybody tried one of these?
Are they heavy?
easy to load up?
how much do they cost?
Who sells them?

Just going off memory, i looked into them a couple yrs ago, think they were around 1300..+ or - hitch. I think the main supplier was out of sask....google koender plastics. They can probably put you in touch with an alberta dealer
