After reading quite a bit on the topic, I decided to add air bag suspension to my Tacoma to assure a level pull with a 17' Casita
. So, for anyone out there thinking of the project for their TV, I thought I would summarize the instillation.
I bought a Air-ride brand kit for about $210 and installed it myself. The instructions are pretty good and it took me almost exactly three hours start to finish. Let me add that I was going very slowly checking everything multiple times for alignment and that it was about 95+ degrees in my shop. If you regularly do mechanic work you could do the install in two hours, or a little less.
The lower bracket attaches to your springs with u-bolts and on my truck model, the upper bracket requires that you drill three holes in the frame and use the included self tapping screws. ALL needed hardware was included.
Tools required were basic sockets, wrenches, C-clamp, and a drill. All in all, a pretty simple kit to install.
