I ordered some Walbernize from them yesterday, really nice guys and very helpful.
Along the same lines, is there an online shop that sells accessories in canada, similar to Campingworld.com? I was at 2 or 3 of the local RV dealers today and couldn't beleive the prices they were charging for certain items.
Additionally, if you do order things from the states, if you can reques that they ship via USPS (US Postal), there are no brokerage fees and if it is an American made product there should be no duty charged, just GST. Avoid UPS at all costs, your item could cost you double what it should simply due to their brokerage fees.
