The OP, Murphy744, has what appears to be leafs under his, done by 'Deaver Suspensions'
Sparky, aka: Karma, did his own swap with A-liner parts.
Very cool campers! I like the fact they are hard sided, yet compact for towing.
HI Bill,
Yeah, I did use Aliner parts. I thought that Murphy (the OP) also used Aliner parts. If he used leaf springs, the work required would increase significantly. And there is no need to do this. Aliner sells most of their trailer models with an "off road" option which would use the same basic axle I used.
As for the merits of the trailer, I like mine a lot. It pulls easily, its light, has plenty of storage, and provides most of the creature comforts of a normal unfolding trailer. One quirk is there is no wall storage because of the way it folds. All storage is in cabinets at floor level. The dinette and bed are on opposite ends of the trailer and can be left setup for the duration without having to rearrange every day. It works well.
In my case it needs to pull easily. My little Jeep YJ's stock engine is only rated at 110 HP at sea level! Most of my camping is at elevations over 5000 ft. Yes, the Jeep huffs and puffs a lot but gets the job done, just not fast. I have driven the "Million Dollar Highway" between Durango and Ouray without a lot of trouble-just a lot huffs and puffs.
If you have driven this road you know it is a very long up hill climb.
What I like most is ease of setup. Not exaggerating, one person can have the trailer set up in 2 minutes! Of course, the hookups still need to be made. I can also carry a small Honda generator which will power the trailers entire electrical requirements including the air conditioner and microwave (not at the same time) when I camp where there are not hookups.
Inside room is adequate for one or two people. Mine actually has sleeping space for four people by converting the dinette to a bed, but I would not like to actually share that space with four. Since I travel alone, it's plenty big enough for me complete with microwave and 24 inch flat screen TV which I only use for watching DVD's. It has a complete kitchen. It's a very comfortable trailer with its full insulation and air conditioning. That I can actually take it on trails I would never take other trailers is a bonus.
