Just to add to Drifta's recommendations, while I don't have one of their drawer systems, I did have their car back kitchen, and when I bought my 10yr old camper trailer a few years back it had one of their full kitchen with return in it. After one trip when I slid the kitchen out while it was fully loaded, and set it up on the legs so I could move the trailer out of the way, I mustn't have tightened one of the leg supports properly, and it collapsed, damaging both legs.
I rang Luke at Drifta to get a price on a new set of legs and he told me they had upgraded the legs so they had click in buttons to stop this happening. He convinced me to send it up, via their courier for free when it visited one of their suppliers, so they could repair it. When I spoke to him next, he said it was one of their very early builds and was happy to see it was still going strong, and would also give it a tidy up while it was there. I asked about price (holding my breath) and he said no cost, he was happy to replace the legs and make sure I was a happy customer.
I got the unit back about 2 weeks in total, because they were a bit busy, same deal free delivery if I picked it up from their suppliers again. When I saw it, it was like brand new again. They had fitted the new legs, replaced the slider plastic with new type (the old one had a broken bit from b4 I bought the trailer), fitted a new water hand pump, sanded a few nicks and scratches and given it a complete new coat of sealer. I was totally blown away by what they had done, and it didn't cost me a cent.
And you have to remember, I didn't even buy the unit from them originally, and it was just over 10 years old when I sent it up there.
So, all I can say is, you'll definitely be looked after by Luke and his team. Pretty hard to find that level of customer support these days.
