bkenobi,
If you do opt to use the TL hitch, and want to use an extension in the future, you would want to get the hitch for nuse with the tie downs that utilize the tie down extension with the hitch, rather than frame work brackets. As far as the TL hitch/tiedown/extension--TL is second to none! There is a short vidieo or picture out there somewhere of a truck and camper that got into a roll over situation, and the truck camper remained tied to the truck. While we consider price versus build, I beleive you get what you pay for, and not an enthusiast of risk management building. Always better to overbuild, than underbuild. TL tests there equipment that they sell, and recently were able to uprate their magnum hitch to 30K tow rating through DOT testing. Call them and ask.
