Axle Risers

Jerry, you might consider this, travel trailers have been running on the tires and axel config for years and I personally have not heard of very many axel related problems related to clearance .

Originally posted by jdsanders Thanks for the info on 15" tires and pics.  That is great info that switching from 14" to 15" tires will only raise my 2010 RP-174 only one inch.  I guess that would help but I prefer to raise it 2"-3". I understand the risers raise it 4".  What about switching to 16" tires and raising the fenders?  You do understand I am trying to raise the axle too?

Not quite sure why you are trying to raise the axle as well.There is plenty of clearance given the fact that there is no differential pumpkin hanging down in the center as with a rear axle of a typical Truck.As the wheels traverse a bump,the axle rises with it.

Unless of course one where to straddle a 8" boulder in the middle of the road,that would be a problem.But even the worst of roads that is unlikely and speeds traversing would be very slow.

The 4" axle risers,better to be called "body" risers" work well on steep inclines keeping the rear stabilizer jacks from leaving their mark in the asphalt.

The 205/75/15 tires are 1" larger in diameter then the stock 205/75/14 tires effectively gaining 1/2" of axle clearance to the ground (half the diameter gain) Raising the Pod 4" with the available risers is fine.The extra 2 to 3 inches that you would like would require custom fabricated riser blocks and unlikely to have R&D or any engineering or testing.

In my opinion not worth the extra effort,money or risk for an inch or so difference.

A 16" tire for an additional 1/2" axle clearance ,over a 15",is certainly doable.Quite a large and heavy tire though.The added weight and rolling inertia may work the brakes a little harder.

I am bottomed out on my rear stabilizer jacks a time or two and am thinking about installing axle risers on my RP174.  Thanks above for all the pros and cons of adding the risers.

I would prefer to raise my 174 only 2".  Rather than installing axle risers, I am considering changing the 14" wheels and tires for 15" in order to raise the axle and camper 2" or more.  Has anyone on this forum done that or do you know anyone who has?  I assume I would also have to raise my fenders.  What are the pluses and minuses of doing this?

Rabbit is right, think 10, when driving under bridges, overpasses etc, if you got a pod, on a 1 to 10 scale with 1 being no fun and 10 being we are really having a good time, think 10, when approaching bridges, going into gas stations with that ugly flat roof, fast food joints (of which I try to avoid at all costs) I sometimes forget they have thoses pesty little awnings that stick out. 10 feet of pod altitude can make a mess of a Arby's awning, I have to change modes when towing the pod, its kind of like taxing an airplane, they are not very long but really wide, my old 1946 taylorcraft wss 34 feet wide wing tip to wing tip and when on the ground you had to think when you were taxiing. My wife Donna has a friend at work that got a pull behind and guess what, they forgot about the height, went under an overpass and sheared off the roof a.c. Ouch, Have fun, Be safe.
