No, there isn't an alternative solution unfortunately as they are dedicated spring loaded for the application so they need to be extremely tough. One of the hinges recently snapped on our Dometic RM7270 freezer box door so decided to buy a pair and replace the two hinges at the same time. The problem is that plastic age hardens over time and becomes brittle so that's why I decided to replace the two hinges. Yes, they are expensive but if the old hinges are original they have lasted 18 years so the new ones should last at least another 15 years so not an expensive item if you look at in the long term. I purchased a pair two weeks ago on Ebay for £47.95 (seller has 100% positive feedback).
Sadly not really, if I'm not mistaken and they are similar to mine, they are dual purpose in as much as not only the hinge on which the freezer door pivots, but also the closing springs which keep the door shut tight and the freezer compartment functioning properly.
Highly unlikely that ANY adhesive (certainly NOT Superglue!) would be strong enough to cope with the loading of the closure springs if attempting to stick any stressed parts back together.
Everything caravan/MH specific is outrageously overpriced, and unfortunately if and when the time comes to repair/replace we generally just have to suffer the cost.
Only alternative I can think of is try a caravan breakers for perhaps a complete freezer door (unlikely they'd only sell the hinges), but may not be that cheap, and it'll be an old unit that may have limited life (those hinges will have been under stress already for some number of years), so not necessarily a truly economic purchase if early failure occurs.
Do shop around for new hinges, the prices do vary quite a lot and some savings can be made.
Thank you for your replies I have decided to bite the bullet and have bought two from Cannock caravan accessories they will arrive tomorrow, I hope they will not be to difficult to fit

I have fitted my two new freezer door hinges today. The way to tackle the job is to remove the freezer door by the two securing screws (one on each hinge) on the underside of the freezer door in the fridge compartment. Once they have been removed, the freezer door slides out forwards from the fridge with both hinges attached which will spring back on retraction. Each have two screws (4 in total) which screw into the freezer door itself which you remove and withdraw each hinge from it's slot. Attach the new hinges in reverse order but the tricky part is trying to get the freezer door back into the fridge compartment as the hinges are spring loaded and you can't see underneath so a mirror is very convenient at this stage. However, the solution is to locate the small spigot on the bracket into the matching hole under the freezer box which you will hear snap into place. Once that is achieved it's a matter of inserting the two securing screws back into place. Maybe it sounds a bit complex but it's a simple task that takes around 5 - 10 minutes.
