Well, I'm soon to officially be the owner of a brand new Catrike Road. So, now I'll have a tadpole and the wife has her delta. We have a Toyota RAV4 for transport and I know that the Road will fit in the back of it, but we still have to haul hers some way. I was searching the internet and came upon the Alpaca 1500 series bike racks. The make one that mounts a delta and a tadpole at the same time. I like the look of it, and the price isn't that bad. I could make one myself, but by the time you put the cost of materials in, the rental of a welder and other associated items I'd probably be pushing the Alpaca's price anyway. Anybody have one of these (not necessarily the delta/tadpole combo)? If so, I've got a few questions I hope you can answer 1) How is the construction of it? 2) Is mounting the bikes that hard? 3) Is the mount stable? 4) Is it aluminum based or steel?
