Here is how I made an A-frame jack block that saves considerable time and strain when hitching and leveling a travel trailer. Folks with manually cranked jacks will really appreciate the work it saves.

Using 2-by-5-inch boards and nails or screws, assemble a stair-stepped platform (see diagram).

After the trailer is parked, determine how much front-to-rear leveling will be needed. If the A-frame must be raised considerably, place the jack post on the highest step of the block. Conversely, if the A-frame must be lowered significantly, select the lowest step on the block.

After using this device a few times, you will be able to quickly judge which step to use to minimize the work at hand.

    I have a question, I recently bought a 2010 25 foot Dutchmen travel trailer. I notied on the lower panel on one side a small area of corroded metal appeared. I appears that the metal is being eaten away from the inside out. After a few months I noticed that it was happening at the same level along the same side in various spots. I took it to the dealer who called Thor (the manufacturer) and they could not give an answer as to why this was happening. Plus they would not cover the $1,300.00 to fix the problem. My question is this has anybody ever come across this problem before. If you have an answer please let me know. Thanks: John T. Ronald Seattle, Wa.
